Hitechpcb is a professional manufacturer of copper based printed circuit board (PCB). We produce metal-based MCPCB, aluminum substrate and copper substrate PCBs. with short delivery time, strict quality and excellent service. What is Copper Based PCB
To shield against emissions, there must be a barrier of an electrical conductive material. Shielding laminates provide an economical and effective solution to this problem. Most of our materials consist of a metal foil (usually, copper or aluminum)

Wanted to know if there was a good "to go by" tip other than the customers(if it helps current req.,10% of 30% of trace) requirements, about pits in the traces on copper plated ceramic substrates? More to the point how many is too many regardless of

Hi, I have a problem I've never seen before so I hope someone here can help. A recent batch of PCBs arrived where the copper lands delaminate with a small pull. Normally you have to pull pretty hard and the whole land comes off the substrate. These

DPC (DirectPlatingCopper) thin film process is a method of prepare copper film using magnetron sputtering technology. This process is a process in which the copper target with the target material is placed in a true cavity chamber, and plasma is generated on the copper target surface by magnetron sputtering technology. The ions in the plasma are bombarded on the surface of the target, which is sputtered into fine particles and deposited on the substrate to form a copper film.

Aging characteristics of new lead free solder alloys are in question by many experts because of higher amount of tin’s effect on the diffusion of other metals, primarily copper, to create undesirable boundary intermetallics over long periods of time and even moderately elevated temperatures. A primary layer of intermetallics, Cu6Sn5 forms as the liquid solder makes contact with the solid copper substrate. This reaction however ceases as the solder temperature falls below that of liquidus. A secondary intermetallic Cu3Sn1, an undesirable weak and brittle layer, is thought to form over time and may be accelerated by even mildly elevated temperatures in electronic modules such as laptops under power. This project was designed to quantify the growth rate of Cu3Sn1 over an extended period of time in a thermal environment similar to a laptop in the power on mode.
