Thanks for the input john but this falls more under a machine problem than what I'm really looking for. But here is a small lesson on MPM printers. Any time that the statement says "Park sensor not made" means that the park sensor wasn't made at th

Thank you for the advice. I am not so concerned with the "2nd reflow", as the same can be said for double sided reflowed PCBA's (the bottom-side parts essentially go through a 2nd reflow). As for the HASL, there is a formula in calculating how much

Also why I am at it. In the book CP-6 Series Maintenance Manul ( Fuji Part # MNT-C060-11.3E ) in Chapter 4 page 4-1-11 it says " The clutches should therfore be cleaned regularly, using the grease cleaner (ThreeBond 2706) provided with the machine."

That is a tough situation and a tough answer for us SMT forum participants. After all, most of us are in the business of placing and soldering components to circuit boards, and you know the saying; you can't make solder joints with an unsolderable su

I have to disagree with you, BillyD. If Craig searches the forum, he will see that the concept of a Pbfree BGA with SnPb paste has been debated many times. You say it is fine. I say it is NOT. There have been several studies done that clearly sho

Russ, By a longer profile you mean a more even slope across the entire profile. Unfortunately I only have a 5 zone oven that is fairly short. How many heated zones are you using? Did you shrink the 0402 pad design and leave less pad exposed out a

The whole point of any forum is to share practical tips and tricks and learn from others in similar positions. If the only thing you're going to say in your posts is "hire a consultant to achieve synergy" you aren't really contributing, it just sound

Question; Do you think it's possible that your customer has got his units mixed up & actually means 0.3 micro inches of gold over 0.5 micro inches of Nickel? That is what I said but their vendor says they are building to print which says 80 uM and i

Hi, What are your thoughts about the article saying that the lead will leach out of the solder joint to the last place to cool, creating a weak point? I have two worries about the report. First, is that we have always used tin lead solder, and le

QE's are the guys that sit in meetings asking the process guys --- "Uhhmmmm....my pie chart here says that we have 11 solder shorts on U1 for the week. WHAT'RE YOU GONNA DO ABOUT IT?" Unfortunately, most QE's dress nice, are tall, have gelled slic
