When it comes to quality multilayer PCB fabrication, Mer-Mar Electronics has emerged as a one-stop-shop. There are number of USPs that we have. The first, we are equipped with start-of-art manufacturing facility that can cater to the most complex multilayer PCB fabrication service. Besides our team of experts is equipped with the necessary expertise and industry best practices; ensure that you do not have to contend with costly errors for any kind of multilayer PCB fabrication services. Our portfolio of satisfied clients stands as the biggest testimony to our superior knowledge and craftmanship.
One printed circuit board that is seeing rising demand is multilayered boards. Not without reason; the drive for miniaturization in electronics makes multilayer PCB fabrication the most suitable. With limited space, single or double-sided PCBs aren’t a possibility. Additionally, in a multilayer PCB, the presence of different layers offers a conductive route for the connection of components and passage of signals. This is why all complicated designs need the support of multilayer PCBs. Some of the other advantages of multilayer PCB fabrication include:
- They are light weight as the conductors required for separate PCBs are reduced.
- They are reliable as also more durable.
- They support high component density.
- They support implementation of complex circuits.
- They are known for their performance as they provide high capacity and speed in a smaller footprint.
- Multilayer PCBs can be manufactured in both rigid and flexible construction.

Multilayer PCB Repair & Rework
If you face an issue with ripped material or damaged pads or conductors, you can count on our experts to offer the necessary repairs and rework of multilayer PCB with a high degree of precision.
The broad steps of multilayer PCB fabrication are as under:
This process involves cutting the copper-clad board into smaller boards that can be made on the production line.
This step involves transferring the inner circuit pattern to the PCB board. This involves multiple processes such as inner layer sticking, exposure and development and etching.
This process helps to remove contaminants such as oil and impurities on the surface. It also helps to increase the specific area of the copper foil. The oxidized surface also isnt affected by moisture.
The process of lamination involves bonding layers of circuits by means of B-stage prepeg. The discrete multilayer board is then pressed together with the adhesive sheet into the multilayer printed circuit board.
The use of a mechanical drill at high speed ensures through holes on the multilayer PCB.
Decontamination and sinking copper
The purpose of this process is to metallize the through hole. A three part process, this helps in decontamination, copper sinking and thickening.
Dry film and pattern plating
This process is similar to the inner layer graphics transfer as it uses photosensitive dry film to print circuit patterns on the board.
Wet film solder mask
The idea of adding the solder mask is to prevent short circuits between lines, insulation and resistance to harsh environment.
In this process, the screen for the printing plate is produced followed by printing character ink on the plate and finally drying of the ink.
This involves separating the delivery graphics from the large panel. Many capacity parameters such as shape tolerance, inner corner size, safety distance between figure and edge of the board are considered.
Commonly used electrical testing includes needle bed test as well as flying probe test.
Electroless tin plating process uses chemical deposition to deposit tin on the PCB surface.
Largely this consist of the following methods: Optical Inspection – With AOI testing equipment, the machine scans the PCB and displays any defects.
Target Inspection Confirmation
This is a process of visual inspection that confirms or eliminates defects.
This is menat to repair or scrap confirmed defects.
There is a wide variety of packaging available including mositure-proof packaging, anti vibration packaging and more. Typicaly vaccum packaging is commonly used.
