Here you will find a number of different laminate materials used to fabricate printed circuit boards for advanced electronic applications. Among these are materials with a range of dielectric constants, low dissipation factor, and controlled mechanical properties....
How To Select PCB Core Materials

How To Select PCB Core Materials

Selecting PCB core thickness becomes a problem when a printed circuit board (PCB) fabricator receives a request for quotation of a multilayer design and the material requirements are stated either incompletely or not at all. This sometimes occurs because the...
How to generate Gerber and Drill files from Eagle

How to generate Gerber and Drill files from Eagle

When you finished your design in Eagle, the last step before sending it off to the fab house is to generate gerber files. Autodesk EAGLE includes a handy computer-aided manufacturing (CAM) processor that allows you to load a CAM file and quickly generate the specific...
What does PCBA test mean

What does PCBA test mean

  The functional test after assembly of the PCBA circuit board is generally called FVT (Function Verification Test) or FCT (Function Test). Its purpose is to capture the poorly assembled board and install it through the analog circuit board. Full-featured testing...
