KM-3 board

Product Detailed:


With the miniaturization of electronic components, the developemnt of high-integrated and high-property automatic assembly machinery and the progress of welding technology, high technology and high-density assembly technology of  automatic machinery have a rapid development.

 

Thus, KM-1 carries out the new punching technology, making the punching temperature low ( 40℃~70℃), to meet the need of times.

The process of this produce is that insulating paper, having been bleached and pickled, impregnates with MTO (Modificated Tung Oil) phenolic resin; then covers with Copper Foil; at last, practises Hot Press. It has two categories----double side and single side. It is capable of good electrnic property and poor water absorption. It is designed for electronic equipment, domestic electrical appliances and printed circuit boards in automatic machinery, which is made under thewet and high-frequency  circumstances.
