Why does everyone tell me smocks will prevent ESD. They're not grounded, so how can they bleed or prevent ESD? They may not cause any ESD, but they sure don't come close to a heel strap or ESD shoes. OK, maybe from a "management" standpoint it mak

SN100C, not as aggressive towards other metals as are other High tin lead free alloys. Why? Sn63/pb37 The lead prevented the tin from being very aggressive. SAC305 no lead, silver instead. Silver doesnt block Tin from it's aggresiveness. SN100C no si

Hi Folks, I hope someone can help me, Is the homeplate stencil design (for reduced solder paste) the same for preventing solder balls as it is for reducing tombstones? i.e. the reduction of solder paste under the component termination. I'm trying to

The lock is manually being able to twist into the lock position and unlock by twisting in the opposite direction. I highly doubt that this is the real problem. First check the rings on the tool to see if they are too worn to hold in the mount head. S

My background is in I.T. Here's what's likely the cause. It's old and worn out. Not much else to offer technical wise. Hard drives are mostly permanently sealed to keep dust out and have moving parts. Eventually they wear out. The way to prevent fail
