What is PCB Assembly?

A printed Circuit Board (PCB) Assembly is the process of soldering electronic components onto boards. They can be installed either using surface mount technology (SMT) or through-hole technology. You can use both also.

How do you assemble a PCB?

We can mechanically connect varied electronic components by using different conductive pathways, traces, and tracks. It also includes different components to be etched from laminated copper sheets and then put onto a non-conductive substrate. Finally, the component leads are attached to the PCB layout with soft metal soldering.

Why is PCB Assembly service so important?

With the growth in the manufacture of electronic devices like laptops, gaming consoles, mobile phones, televisions, etc. it has become inevitable to have a PCB assembly without which these devices cannot operate. One needs efficient and precise PCB assembly services for their electronics.

Why should I choose Mermar electronics for PCB services?

We are one of the leading PCBA electronics companies in the USA offering our customers a full range of assembly services. We focus primarily on the fabrication and assembly services of PCB prototypes. Mer-mar electronics has expertise in the assembly of high-density and high-mix printed circuit board assembling. So, whether you need a low-mix assembly or a high-mix one, low volume prototyping, high-density products, you can rely on us.

Do you assemble boards fabricated by another board vendor?

Yes. Provided they maintain high-quality standards. We do not make any compromise on the quality. So, if the vendor has good quality assemble boards, then we can take it up.

What is your standard specification PCB?

Our standard boards are of the following specifications - FR4, 1oz copper weight, white silkscreen, 1.6mm thickness, lead-free (if required), green solder mask.

Do you have any lower limit on prototype assembly?

There are no minimum order quantity requirements and we can assemble even on a single board if you require.

How do you reduce the circuit board costs?

We focus on the prototype or layout to reduce the additional cost you may encounter in the later stages. The PCB price costs can also be reduced by taking care of the following elements like raw material, board thickness, copper thickness, min hole size, total hole quantity, layer counts, etc. You can see how you can optimize these to reduce the overall costs.

Can you do a partial PCB Assembly?

Of course. We do partial PCB assembly for both consigned/ kitted orders and for turnkey.

What do you do with the unused parts?

We return all the unused parts to the customer itself whether consigned or turnkey.

Do you have any specific requirements for BGA components?

The component footprint must adhere to the manufacture’s recommendations especially the pad size and mask clearance.

What does your estimated price include?

When you come to us for a quote, we provide you the pricing details that include solder stencil, tooling, and assembly labor for loading the components. It also includes component pricing.

What if I see problems or issues in the loaded boards?

You can contact us when you see any issues on your loaded boards. We will dig into the issues, find the root causes, evaluate them, and repair them as required.

What PCB standards do you follow?

We have been certified to ISO 9001:2015, AS9100 rev D Certified, RoHS, ITAR, and also compliant with the US Department of Commerce’s Export Administration.

Will you sign the NDA?

Yes. We do have a non-disclosure agreement with our customers to protect their interests.

How do you ensure the quality of your PCB assembly services? What can I do if I am not satisfied with your PCB?

We deploy qualified technicians to work on your PCB who adhere to the highest standards and conform to the customer specifications. We make sure from the start to meet all the industry standards. With consistent product quality and timely upgrades, our rejection rate for assembly defects has been below 0.7%. However, if you are not satisfied with our services, you can let us know anytime. We will review your request and address the issues.

How much cost do you charge for a custom PCB?

The cost varies depending on the size of your PCB. One board differs from the other and so does the cost. Our team would help you arrive at the best possible solution specific to your needs. Size, number of layers, board laminate type, and number of boards required have an impact on the cost.

PCB Assembly Technologies

There are three methods to construct a printed circuit board assembly.

Surface Mount Technology (SMT) – SMT is the process of mounting the electrical components directly on the PCB surface. Leads are soldered on PCB surface directly instead of using hole mounting. We are known for our accuracy and follow the right SMT techniques to yield best-in-class SMT PCB assembly for electronic devices of all sizes. SMT is beneficial where there is limited space.
Through Hole Technique – We provide end-to-end Through-hole assembly services from prototype stage to production. We adhere to international standards and our services comprise both manual techniques for handling complex assemblies and automated techniques for small-volume production. THT provides strength to the components using the state-of-art wave soldering method.
SMT and THT Assembly capabilities include –
- Full Through-hole Assembly Line
- Low to High Volume Production Assembly
- ESD Controlled Area
- Single and Double-sided Assembly
Mixed Technology – We render mixed assembly services with Surface Mount Technology (SMT) performed first followed by Through-Hole-Technique (THT). We ease the process in mixed assembly technology by selecting the optimal blend of layout and raw materials.
