Multilayer Printed Circuit Board Manufacturing Process

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.

Multilayer printed circuit board manufacturing process.

Because it is made by electronic printing it is called printed circuit board. Multilayer technology has been producing quality printed circuit boards since 1986. The whole process needs to be done in an esd safe and cleanroom environment. Pcb or printed circuit board is an important electronic part and the support body of electronic components.

Special manufacturing setup and equipment are needed for 8 layer pcb manufacturing process. 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. 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. 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.

Manufacturing multilayer circuit boards is a straightforward process but does require a high level of attention to detail. This creates a blank printed circuit board with the copper everywhere on the surface. Electronic products in the production process there will be a printed circuit board production process. Both sides of the core are covered with a uv sensitive dry film resist that is hot roll laminated in place.

To guarantee pcbs be manufactured with your expected quality performance and durability you have to pick up a pcb manufacturer which has high level of expertise and a focus on quality at each stage. As you can see a lot of work goes into manufacturing process of printed circuit boards. Components are generally soldered onto the pcb to both electrically connect and mechanically fasten them to it.

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.
