| I was wanting to know if double sided reflow can be done with a metal plated BGA on topside. We would be running bottom side first. My boss seems to think the only way it can be done is by placing glue dots on the bottomside compoents because the

| Everyone- Ben: You are 100% right. Too often we seem to drift into the pitfall of knocking a product or company and the end result might just be that we did not know how to use the equipment or material. As for myself, I have found that when I h

Dave, Hany, I was actually surprised to hear that topside SMT components can reach such a high temperature during wave soldering. If this is the case then the concern for component damage is very valid. This morning I discussed this issue with Jac

Hello! I have a strage problem, we made some production with uBGA, BGA, 0201, 0805, and other type of component. We didn't put the uBGA and 0201 and BGA on the board at the end of the line we look a our solder joint and surprise the solder made a

Guys, Thanks for the input. Its a Opto-Electronic project I'm working on for a customer with a device on a ceramic substrate. Yes, I did learn from Indium that 007 is no-clean and has a high-solids content. They reccommended using TacFlux 010, which

cvrgrrrl Your first thermal cycle with imm silver should be the easiest to solder. That you see copper indicates you did no soldering, got no wetting, produced no intermetallics, etc. Tell us again which components did not solder? Wuzzis "plug" t

Several places I've worked did not allow radios/players of any kind, with or without headphones. The one place that did had a policy that I thought was pretty good - Operators had to be there at least 6 months before they could wear one (that way th

The IPC 610 actally conflict's with 7095 which give's a better indication of what's acceptable. I believe that IPC are reviewing both. Motorola did a bunch of work before basically showing that void's aren't that bad up to a certain size, I think pro

We are currently NOT using bulk, even though we looked into as a means of reducing machine time and component cost. Unfortunately, since bulk cassettes did NOT take the industry by storm as it was predicted years ago, we were stuck with long lead ti

I once worked for a new branch of a company. We had a board where one of two tants would shift in the oven. When I phoned up HQ because they had ran the board before as soon as I said the product name their guy said "C148 shifts in the oven" He knew
