| Is there any problem using SMT on gold boards? 15 years ago we were told not to use gold boards, but I can't remember why. Judging by the other postings it now appears to be common. Only problem I see is that the nickel should be plated, not ele

| We have mixed to negative feelings about Omikron, but I beileve it is due to problems with the board fabricator rather than the process itself. When done properly, our Omikron boards have had very good solderability. However, we have had several

Our Electrovert UPK445 needs a new solder pump motor. The Machine is down. I'm taking a huge chance with Specnor. If the motor doesn't come in or if it doesn't work, then I'm dead. They told me I'd have the motor next day. They kept trying to sell me

Everything went smoothly. I had the motor in less than one day. And I saved $690 from Electrovert's $1170 price (slightly different model but it works great!). | Our Electrovert UPK445 needs a new solder pump motor. The Machine is down. I'm taking a

Are you using a HASL board or an organic protection on the pads? This will help determine as to whether paste is necessary or just a very active/tacky flux should be used. Tight process control will also help in the reflow oven. Many users don't wan

I agree with the response and strongly recommend that you use the "home plate" design to reduce solder ball entrapment, and that the under cut for the 0402's in particular be 80% of the pad size. Solder slump is typically about 1.2 to 1 so spread wi
