Double side PTH and Multilayer PCBs

 

Double sided PTH PCB: Copper Plated Through Holes

• Standard products: PTH, track width > 150 microns,  FR4, photosensitive soldermask

• High density: PTH, fine track width ≤ 150 microns, small holes, FR4

• Special types: thick copper, thin core, conductive jumpers, shielding planes, golden PCBs, hard gold, non PTH, punched, laminate stuck to aluminum plate, etc…

 

Multi layer PCBs :

• Standard products (4, 6 layers), FR4, photo-sensitive soldermask

• Special types (thick copper, thin core, hard gold, etc...)

• High layer count (8 to 20 layers).

• High Density Interconnection (HDI): micro-via technology, build-up construction, laser holes, very small tracks, etc…

• Low cost CPTH: polymer conductive holes with copper paste. 4 layers, FR4

• Back panels : thick PCBs, press-fit technology, large size PCBs
