Multilayer PCB Manufacturing

Single Connection Point

If you are building lower frequency applications, we would help build them with high reliability and accuracy using single connection points. We also make sure to not make any mistake in correctly routing the signals so that the operation of your whole board will not be risked due to the poorly designed ground strategy. We make sure to prevent electrical shocks and protect the safety of your equipment and electrical device.


Multilayer PCB Lamination

The multilayer PCBs are fabricated in various layers and then bonded with lamination. We use the process of building up successive layers of materials and bind them for strengthening and greater protection. We also make sure that the components are waterproof and do not inadvertently conduct current or signals through effective lamination. We also make sure to customize the laminates to meet your specific requirements. Stay assured that we maintain the structural integrity of your circuit boards.

Multilayer PCB Board

Multi-Functional Printed Circuit Board Assembly

We build multifunctional assembly by reducing the number of components and installing circuit devices for additional functions in the PCB. We couple a microphone cell unit along with a printed circuit board (PCB) and improve the sound quality. Multifunctional PCB assembly conveyor is mainly used for visual inspection, manual assembly, PCB buffering, and equipment linking functions. Especially if you have space limitations, we help you build multifunctional assemblies that serve all your purposes.

Multilayer PCB Assembly Techniques

Mer-Mar electronics has a brilliant in-house team who have the capabilities to handle the complex designs of a multilayer PCB. We stack all the layers meant for routing by adopting the following mounting technologies for the multilayer PCB Assembly.

  1. Through-hole
  2. Surface Mount
  3. Mixed

Surface-Mount Technology – We are skilled at placing sensitive components that are compact in size accurately onto the surface of the board. They could be resistors, diodes, integrated circuits, or even miniature components. We maintain the manufacturing efficiency intact and follow automatic mounting PCB assembly process from solder paste printing and reflow soldering. We maintain the quality of soldering by focusing on the quality of products carried during the solder paste inspections.

Through-hole Technology – We use through-hole technology on your PCB assemblies that contain large components like capacitors, coils, etc. Depending on the type of your board under multilayer PCB, we include a variety of components. We accomplish the through-hole mounting by deploying both manual and automatic procedures. Our professional engineering staff know how to precisely place components on the corresponding positions based on your design files submitted to us. We also conform to regulations and operational standards of the through-hole mounting process for guaranteed quality. We also immediately inspect to determine whether the components are placed accurately or not and rectify them at the earliest. We are also experienced in wave soldering for the accurate soldering of components onto circuit boards.

Mixed Technology – As the electronic products have become increasingly complex, we can build integrated and smaller size PCB boards. We use both through-hole components and SMD components where we collaborate through-hole technology and surface mount technology. Any intricacies around the soldering is a complicated process but we better arrange the sequence of surface mount technology and through-hole technology.

Multilayer PCB Assembly Testing Capabilities

After the completion of multilayer PCB assembly, the assembled boards will be tested for the functionality, bug fixes, quality checks, etc. Any misplaced components, errors & misalignments will be checked and corrected. Through a series of tests, we check the fate of a malfunctioning board as per the laid-out standards and correct it before we ship it. The tests also meant to check the quality of the multilayer PCBs in addition to identification of any potential problems. These regular checks ensure that the errors are found and fixed promptly that saves resources like time, labour, and materials.

Some of the testing methods Mer-Mar Electronics perform are –

Manual checks – We still rely on manual checks though we adopted automated testing. Especially, for smaller batches, we perform visual inspection to ensure the quality of the PCBs. When the number of inspected boards increases, we do not push ourselves to the edge of optical fatigue which may result in less accurate inspections. We then go for automated tests.

Automated Optical Inspection – We use this inspection type for larger batches of PCBAs. With high-powered cameras, we view the solder connections and recognize any lower-quality solder. High quantities of PCBs are tested at a very high speed in a relatively short time.

X-ray Inspection – We use X-ray inspection methods especially for the multilayer PCBs where the number of layers is more. Using this, we view through the layers and visualize different layers for identifying the potentially hidden problems.

Functional Testing – This would be the final inspection test where the tests put these multilayer PCBs through a series of tests, and monitor their characteristics. We check it by simulating different circumstances like high voltage, current, signal outputs, unacceptable fluctuations, peaks outside the predetermined range and see if the PCB works without fail.

Any deviation from the usual will be corrected, and failed ones would be recycled and scrapped as per the due procedure.
