China Wholesale Embedded Pcb Manufacturers - 8 Layer ENIG via-in-pad PCB – Huihe
China Wholesale Embedded Pcb Manufacturers - 8 Layer ENIG via-in-pad PCB – Huihe Detail:
The most difficult thing to control the plug hole in the via-in-pad is the solder ball or pad on the ink in the hole. Due to the necessity of using high density BGA (ball grid array) and the miniaturization of SMD chip, the application of in tray hole technology is more and more. Through the reliable through hole filling process, the in plate hole technology can be applied to the design and manufacture of high-density multilayer board, and avoid abnormal welding. Huihe Circuits has been using via-in-pad technology for many years, and has an efficient and reliable production process.

Function of plug hole
1.Prevent the tin from passing through the conduction hole through the component surface during wave soldering
2.Avoid flux residue in the through-hole
3.Prevent tin balls from popping out during wave soldering, resulting in short circuit
4.Prevent the surface solder paste from flowing into the hole, causing virtual welding and affecting the fitting
Advantages of via-in-pad
1.Improve heat dissipation
2.The voltage withstand capacity of vias is improved
3.Provide a flat and consistent surface
4.Lower parasitic inductance
