Overcome the factors that slow down PCB Manufacturing

By | Date posted: | Last updated: December 24, 2021

Printed Circuit Boards are becoming ubiquitous in today’s environment where we tend to use enough and more electrical devices in many aspects of our lives. Circuit boards containing the complex circuit array that they do, both their design and quality is of tremendous essence when it comes to the efficiency of the final product.

Complexity of printed circuit boards also increases their chances of failure on account of factors such as oversights in design, errors in drilling, over etching and more. In today’s highly competitive market where go to market time is of essence in the success of your product, you certainly cannot afford to lose time. Each error and potential failure of the PCB can in turn cause costly delays. What you need, therefore, is the right PCB partner who can offer you quick turnaround times without compromising on quality. A close look at some of the common factors that can slow down the PCB manufacturing process is imperative so that you can keep these factors in mind in choosing the right partner. Here is a handy checklist that you can refer to while making your choice:

Delays in Prototypes

If you are setting out on a new business or expanding your product line, the one thing that you need for sure is a prototype. For the same you need to work with a company that has a quick turn around time when it comes to developing prototypes. Not only do you need a manufacturer that can provide you these prototypes without delay, you also need someone reliable who is able to understand your requirements and deliver a prototype that is as per your requirements. Delay in receiving the prototype or receiving a prototype that does not meet your requirements can equally lead to a whole lot of delays down the line that slow down the manufacturing process. It is imperative therefore that you choose a PCB partner who has a proven track record when it comes to both delivery time as well as understanding your exact prototype requirement. Only with such a partner can you be sure that the prototype will work the way it should and therefore your timelines will not be jeopardized.

Creating PCB boards your self

Given the fact that you could experience delays in receiving prototypes from some PCB partners, you may often be tempted to create PCB boards yourself if you have some amount of technical knowledge. This approach, however, can lead to a host of costly mistakes besides consuming a lot of your time, which could otherwise be used in other productive aspects of business. The net result could therefore still be delayed time to market. Spending some time to research a partner who is extremely professional and can deliver PCB boards on time and with accuracy is therefore a productive means of avoiding delays.

A professional partner will take a number of factors into account at the design stage itself. These include proper placement of products which if not done correctly can among other things lead to overheating. In fact the risk of creating PCB boards your self, is often burned components. Also with a quality partner you can rest assured that the components that are used are of high quality and that traces and pathways are in order. There are a whole lot of issues that need to be kept in mind such as proper soldering, sufficient board thickness and more which the PCB partner on account of his vast experience will be privy to, but which you may not be exposed to and therefore could easily miss.

Setting unrealistic expectations

Another aspect that is known to slow down PCB manufacturing sometimes lies not so much with the PCB partner but in the fact that one tends to set expectations that aren’t realistic. These expectations may be by way of cost of the product or turnaround times. It is imperative that you undertake through research so that you set expectations that are not out of sync with reality. This will in turn help you in creating a product roadmap that will be sustainable.

On the other hand, on occasions you could also come across PCB partners who might offer you turnaround times that seem extremely appealing but which are at the same time, unrealistic. With your research in place this should raise red flags as in case you go ahead with these unrealistic expectations you are likely to meet bottlenecks on the way that could derail your entire plan.

If there is one common learning thread running through the checklist, it is the fact that enough time and energy should be spent in doing a thorough research on the credentials of the PCB partner so that you can consciously avoid these bottlenecks.

How 5G Fosters the Demand of Advanced PCB Manufacturing?

By | Date posted: | Last updated: December 24, 2021

The demand for compact devices that are a perfect mix of form and function has forever been on the rise. More so, when it comes to smart phones, which is a highly competitive industry and where success or failure of new generation phones determines company fortunes. Compact smartphones not just mean ease of use to the end consumer they also facilitate use of larger batteries, high-resolution displays and more.

So far PCB manufacturers have been able to solve the form-design conundrum by using high-density interconnects (popularly known as HDIs) which allow enhanced function per unit area as compared to conventional PCBs. HDIs help leverage fine lines as well as laser-drilled vias and therefore have helped in the evolution of smart phones in their ongoing miniaturization.

However as we move from 4G to 5G compatible smartphones, the entire approach to PCB manufacturing needs to evolve. One challenge is to cater to millimeter-wave frequencies, which so far were almost exclusively used by the military. However 5G devices have made them accessible to billions.

Within the 5G smartphone, there needs to be a tremendous increase in the processing power needed to support the huge volume of 5G data. In turn, this is also likely to impact battery capacity among other things. Odds are, therefore, that the space available for HDI PCBs will be severely impacted. Also there needs to be the highest degree of precision in setting thin PCBs as there can be the risk of degradation of signal.

The answer to these issues can be the use of mSAP or a modified semi-additive process. With the use of mSAP, 5G smartphone manufacturers are able to achieve the desired device density without the fear of degradation of the signal. With current space requirements having reduced, mSAP allows 5G smartphone manufacturers to ensure that there is seamless operation at high frequencies.

The way that it works is that a thin copper layer is coated onto the laminate. This is an additive process as it is plated in the areas where the resist is not applied. The copper that remains in between the conductors is then etched away. The difference in this process is that while in the conventional subtractive process, the trace geometries are chemically defined, here the defining process happens through photolithography, which calls for greater precision and lower signal loss. Also in the subtractive process, the treatment that is used to etch the lines vertically, oftentimes also dissolves the copper horizontally as well. This can result in a wedge-shaped trace, that in turn can lead to a number of anomalies.

With the use of mSAP, PCB manufacturers can overcome all the hurdles that are a part and parcel of using HDI. However, the important thing is to implement mSAP in a manner that production is maximized and costs are kept at an optimal level so that the return on investment is maximized and production efficiencies maintained.

One way to ensure that production efficiencies are not compromised is to invest in advanced manufacturing tools that offer competitive advantage. To this end, direct-imaging systems are being increasingly used that ensure 10-15 micron line spacing is achieved. In turn this can result in high accuracy and enable advanced localized-registration features.

Direct- imaging (or DI systems as they are popularly called) and multi-wavelength light sources result in consistent uniformity as well as high quality. Additionally, through the use of advanced automated-optical-inspection systems any defects can easily be identified and quality assured. Also with the use of 2D metrology, the assessment capabilities can be further enhanced. Its use can ensure that top and bottom conductor widths are maintained and proper sampling techniques are used.

It is also advisable to use automated- optical-shaping (AOS) systems as these go a long way in identifying opens, shorts and other such defects. With the use of AOS systems, the need for manual repair can be taken away as AOS provides for far greater accuracy than manual repair. In fact not only is it more accurate, it also eliminates PCB scrap. With so many advanced HDI manufacturing solutions available, it is imperative that they are all connected via a software so that every touchpoint is taken care of and troubleshooting is easily facilitated.

With the evolution of 5G smartphones, there is certainly a need for advanced PCB manufacturing which can take into account an increased density of the embedded electronics while at the same time ensuring that there is no signal friction. With mSAP these specifications are met while technologies such as DI, AOI, AOS and more go a long way in both maximizing yield as well as keeping costs under check. As new generations of smartphones evolve, mSAP is likely to become the mainstream production process. It is not a surprise then that mSAP technology is slated to become the key investment project for PCB manufacturers.

In this modern world of digitalization, speed is the prime and basal factor that adds up to the product performance at large. Herewith, the multitude of electronic design is stuffed with a lot of high speed interfaces in addition to the intensified signal speed that the layout and traces of the printed circuit board act as the fundamental foundation element of the system performance as a whole. The rising enrichment in the electronic innovation have resulted in increased demand of the high speed PCB manufacturing and assembly techniques that are best fit for the complex critical PCB requirement including the need of reduced onboard noise in the PCB. Noise on the printed circuit board is the chief deterrent of the overall system performance. This blog highlights the ways and means to reduce on-board noise in high speed PCB.

The PCB design ensuring a level of up-gradation in delivering reliability should set out low level and nominal on-board noise in the PCB’s. Acting as a prime vital stage to get a tough, noise free, high performance PCB assembly service, PCB designing is in the mainstream. For this, the factors of significant concerns include effective circuitry design, issue of interconnecting traces, parasitic components, decoupling and grounding techniques for effective PCB Designing. Above all leads the sensitive structuring and mechanics of the traces- The ground loops and ground noise, stray capacitance, high circuit impedance, transmission lines and embedding traces. For the high frequency requirements that have fastest signal speed in the circuitry, the PCB design aspects should involve the above mentioned significant concerns for a reduced level of noise that in turn give a durable high-performance PCB solution.

Design tips to eliminate on-board noise in high speed PCB

Noise in PCB may adversely affect the PCB performance with the fluctuation induced in the voltage pulse and in the shapes of the current. Take a read to the few preventive steps on avoiding the blunders that can help in enhanced functioning and put a stop to noise in the high speed PCB.

Reduce Crosstalk

Crosstalk is a superfluous inductive and electromagnetic coupling between the wires, traces, cable assemblies and elements related to electromagnetic field distribution. Crosstalk significantly depends on the technique of routing traces. There is reduced chance of crosstalk occurrence when traces are routed side by side. In case the traces are routed parallel to one another, it is more likely to initiate a crosstalk if the trace segment is not kept short. Other ways to avoid the crosstalk are the reduced dielectric height and wider space between the traces.

Strong signal- power integrity

It is prudent for the PCB design expert to cautiously consider the Signal and Power Integrity mechanism along with the analog features of the high speed PCB design. One of the key design concerns for high speed SI is the right selection of the transmission line for the PCB design depending on the requirement of the exact signal speed, the driver IC and other design complexities that can help to avoid on board noise in PCB with rapid signal speed. Power Integrity (PI) also acts as a vital part in achieving the required protocols of high speed PCB design with reduced noise and a constant level of stable voltage across the chip pads.

Prevent Cold Solder Joints

The inaccurate welding process can cause cold solder joints. Cold solder joints can cause problems such as erratic cut outs, static noise and much more. Well! To prevent such issues, make sure there is a proper heating of the soldering iron at the right temperature. The tip of the soldering iron should be placed on the solder joint to heat it properly followed by the solder application on the joint. You will witness a melting at a right temperature; the solder completely covers the joint. Other ways to improvise the soldering method is by using the soldering flux.

Reducing PCB Emissions for low noise PCB design

The adjacent pair stack-up layout is the most desirable circuit layout option to avoid on board noise in PCB. Other prerequisites to get a low noise PCB design with reduced PCB emission includes low chances of splits, add a series termination resistor, use of decoupling capacitor, draw apart the analog and digital ground planes and segregation of the I/O area coupled with the off board or signals on the circuit board that well suit the need of low noise high speed PCB.

It is uncertain to virtually design a noise free PCB with implementing all the above mentioned techniques completely with keeping in mind the requirement of the specific design customization for any PCB project.
