Multilayer Printed Circuit Board Manufacturing Process

Pcb or printed circuit board is an important electronic part and the support body of electronic components.

Multilayer printed circuit board manufacturing process.

The boards are made by using much thinner individual boards one for each layer and these are then bonded together to produce the overall pcb. The manufacture of multi layer printed circuit boards although it uses the same processes as for single layer boards requires a considerably greater degree of accuracy and manufacturing process control. At multilayer technology interaction is the key to our success. Multilayer pcb manufacturing process needs special precaution as there are more chances of cross connections overlaps tracing in copper areas etc.

A printed circuit board pcb mechanically supports and electrically connects electrical or electronic components using conductive tracks pads and other features etched from one or more sheet layers of copper laminated onto and or between sheet layers of a non conductive substrate. Patterning or etching majority of printed circuit boards are manufactured by applying a layer of copper over the entire surface of the pcb substrate material either on one side or both sides. The first process in the production of a multilayer pcb is making the inner layer core the process begins by selecting a sheet of laminate that is the correct thickness and covered with cu foil of the required weight. Electronic products in the production process there will be a printed circuit board production process.

The whole process needs to be done in an esd safe and cleanroom environment. Both sides of the core are covered with a uv sensitive dry film resist that is hot roll laminated in place. Components are generally soldered onto the pcb to both electrically connect and mechanically fasten them to it. Manufacturing multilayer circuit boards is a straightforward process but does require a high level of attention to detail.

Because it is made by electronic printing it is called printed circuit board. This creates a blank printed circuit board with the copper everywhere on the surface. We are an as9100 iso 9001 2008 itar jcp mil prf 31032 certified company. Multilayer technology has been producing quality printed circuit boards since 1986.

As you can see a lot of work goes into manufacturing process of printed circuit boards. Care must be taken to ensure all layers are correctly registered to the required drilled holes despite the deformation stresses produced by the heat and pressure.
