Most ionic contamination testers prompt the operator for the current concentration at the start of each cycle. The normal concentration is 25% DI Water and 75% IPA. Although most machines ask for the current concentration, concentration adjustments

Don't forget repairing the boards all the special tips for the small parts sounds like you might be placing BGA may need a special machine just for reparing that. some places think they need x-ray for inspecting BGA. type of paste that you going to

We got over 500,000 placements per month with two Mydatas for three consecutive months. And I want to say organized Fuji changeovers beat disorganized mydata changeovers. Even though Daxman is right that they can take a little longer to set up. In o

I'll put a vote on MyData, but you might have problems with the volume... If you're buying used on this better off buying from MyData, they have a tendency to buy up the decent stuff off the used market, and anything left noone really wants to deal w

Yes, this scenario is fine. However, BGAs are a different story since the ball is the bulk of the solder joint. In this case, you MUST run a "hybrid profile". Look it up in the fine SMTNet archives (keyword: hybrid profile). I have "been there an

Panapro can be set up for the centroid data in any order. You won't be able to load the centroid data straight into the machine though. At one time I used Unicam to program a mydata. Then we got a panasonic line. The panarep said we could configure

You are making sense. And no you can't go from centroid data to a program at the machine automatically. You can type in the numbers if you want but the machine won't turn centroid into a placement program. Don't you have PanaPro? I thought there w

Hello everyone! I'm a student of electrical engineering currently working on a thesis for my BSc degree. It will be about post reflow AOIs and AXIs, and I'd kindly like to ask you for some help with it. I would like to know if there are any standar

Dear Hegemon, I'm very grateful for your help. There is one more thing that I'd like to discuss with you. I'd like to know if there is any "verification board" or something like that to check if you really did a good job. At the company where I wo
