We had a bad situation with solvent wipe. One of the solvent supply lines cracked and the solvent got on a cluster of air lines. The air line material reacted poorly and we blew what seemed like one airline per day for a couple weeks. I had to cut

Sorry, I am jumping into this late - I'm a new user. Our company is looking to perform an evaluation for a new paste. We are looking at a 63/37 no clean - type 3 or 4. Our technology is currently at 0201s, .4mm pitch ICs & .5mm uBGAs. I have

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."

I tried some SN100C from AIM... On only one array. It flowed well on the chips but did not like the finish on the SOT23's on the board. I did not have enough arrays to mess around, so we switched it over to SAC305 and had no issues. I'm guessing w

Hi Grant, Boy, how do I say this - I might have to agree with Wave Master Larry. (Yeah, yeah - I know; Davef and Dr. Shocker will "burn me" again) "We" also solder large thru-hole connectors on with a selective solder machine. They measure 4 by 8

I see what you're saying - I'm not a process guru by any means. I was going on the premise that SAC melts at a higher temperature than SnPb. Basically I think of it as a BGA is joining solder to solder, unlike an SOIC where it is tinned metal lead t

Ah yes Mechanical Engineers. My previous company hired one Fresh out of College. Ink was still wet on his B.S. degree when he entered the shop. I passed by his desk. He had a CAD drawing on the monitor which he was feverously working on. It showe

I don't remember ever having that problem with my EKRAs, but you might look at how much fluid you're dispensing on to the cleaning medium if this is occurring while you're using wet cleaning cycles. It could be getting saturated to the point of weakn

I found this searching the archives. Unfortunately Bob doesn't seem to have an active site anymore, just references by people he works for. It's a shame, because there was a load of good stuff there. Haven't looked at Phil's site for a while but it's
