Morning all. So today I have been tasked with conformally coating a few of our first run PCBs for a new product line. The problem is that they have already had all the larger caps potted with RTV. Are there any problems with spraying the CC over the

Sounds good. Id like to add that we are not intentionally freezing the paste. Its supposed to be chilled only. I think the t-stat on the fridge is malfunctioning causing the freezing temps. I have new paste coming in today. If things look better I ma

I would reccomend a good location for the 1000, in the dupster. It wasn't even made by Quad, not that its a bad thing. C series are pretty much crap for today's requirements. FYI: Tyco/Quad is offically out of pick-&-place machine designing and manuf

Hi production encountered a problem today. There have been a mix-up of solder paste. We are currently running clean process in one side of board. Unfortunately when PD run the other side process they were able to used a wrong no-clean solder paste.

I have seen good results on OmniFlo 5 for Pb Free solderpastes PROVIDED the boards are low to medium thermal mass and have no high conveyor speed (high production) requirements. Max peak temp you can set on O5 is 280C, enough to get 230C on-board tem

BTU have been around since the start of SMT, with ancient TRS14's still running today with no problems, and bucket loads of VIP's, Paragons & Pyramax's doing good service. Wouldn't use anyhting else (Did like the new Vitronics-Soltec, but couldn't b

Thanks for the info., Mike, and thanks for trying to dig up a little more. I spent some more time digging myself yesterday and found an MSDS for the stuff we use, but no specification. I finally just put in a call to our Armakleen distributor's cor

Great idea... thanks... I've just looked at our CP4 today, and can't for the life of me figure out how to set the board origin. I can't find any mention of it in our maintenance or operator manuals. Anyone out there know how to do this?

You see? Chunks, here has the right idea! To the original poster, you need to show this post to your "Desk Jockey" Process Engineer. That's the problem with some Engineers today. They forget everything they learned in Engineering school, they get
