Via in pad pcb with blue solder mask white legend and immersion gold surface , copper 1oz description of model number sktech-2120-b2: base material : fr4 halogen-free board thickness : 1.2mm solder mask: green surface finish : immersion gold number of milled slots: 0 number of internal cutouts: 0 impedance control no layer count �4 layers final foil external: 1oz final foil internal: 0.5oz with the development of electronic products to the light, thin and small, pcbs are also pushed into high density, high difficulty. Among them, via in pad is one of the topics that engineering designer can not avoid. It is a main part of multilayer pcb and directly helps to save pcb real estate up to 50% for fine pitch bga and flip chip components. The main difficulty for the plugged via is to prevent soldering tin into via or solder mask onto pads. The accumulation of years of manufacturing experience has given us a good control on the pcb quality.
