Study and Application of No-Formaldehyde Electroless Copper Plating in PTH
The electroless copper plating process, which uses the formaldehyde as the reducing agent, is the most important process in PCB through-hole metallization. But it is well known that formaldehyde is harmful to people and environment. Some new electroless copper plating baths which use other green reducing agent were reported in these years. We studied the new baths which use sodium hypophosphite and glyoxylic acid, and the applications of these two baths in PTH. At the same time, we discussed the outlook of these new baths in PTH.
