Here is a formula that may help. C/P C= Component's weight in grams P= Total pad area in Sq. in. Must be less than or equal to 30 Parts larger than a 68 pin PLCC should use an adhesive. Hope this helps.

surface tension is what holds the parts on when solder is flowing I would add some glue under the parts that I placed on the frist side the glue will add more surface tension. this is if you have a glue dispencer in your line already.

Make sure your oven conveyor is running smooth as well. One bump or bad vibration will knock parts off too. Lowering the bottom zones in spike zones will help too.

No. It took you 5 sentences to tell me absolutly nothing. Let me guess, you're a consultant to managers or worse yet, a manager?

There are several out there. We will be doing some proprietary BGA installation in-house and I need a rework station. Has anyone had any experience with Focal Spot RD-500? Air-Vac DRS25? Or is there a better system out there for occasional to light u

It is an FIP-II 4000. I rather do it through here so other people can benefit. Thanks

We replaced SA-6 with a new one and the IP2 is up and running. I don't know if you're still looking at this thread but I wanted to thank you and post the result so other people benefit. Thanks so much for the help. Rodrigo
