Multilayer Printed Circuit Board Manufacturing Process

Multilayer technology has been producing quality printed circuit boards since 1986.

Multilayer printed circuit board manufacturing process.

Manufacturing multilayer circuit boards is a straightforward process but does require a high level of attention to detail. At multilayer technology interaction is the key to our success. 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. As you can see a lot of work goes into manufacturing process of printed circuit boards.

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. 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. Multilayer pcb manufacturing process needs special precaution as there are more chances of cross connections overlaps tracing in copper areas etc. Components are generally soldered onto the pcb to both electrically connect and mechanically fasten them to it.

Electronic products in the production process there will be a printed circuit board production process. Because it is made by electronic printing it is called printed circuit board. 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. The whole process needs to be done in an esd safe and cleanroom environment.

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.

This creates a blank printed circuit board with the copper everywhere on the surface.

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. Pcb manufacturing process flowchart step by step step 1.
