Flame retardant epoxy-glass circuit boards are made using brominated epoxies,with the bromine atoms providing the flame retardancy.In a fire,these boards can give off toxic gases.Bromine free epoxies can be used,with other additives being used to pro

The solder paste formulation is different 63/37 is a tin lead alloy so t here is one difference from a lead free. Yes you can get no clean lead free products but if you compare the amount of visible residues they will be normally higher. So far most

If you require several changeovers per shift the quick connect closed loop pump option would be your best bet.You can change between pump and blades within minutes. Hoever if you have several different size pumps a simple pump switch over would be pe

Does anyone have knowledge or experience with Pin & Paste on boards that are .095" thick? The boards would have mixed technology, PTH, fine pitch, and BGAs. I did a search for this info and nothing touches on this particular subject, thicker boards.

We experienced a random no contact at ATE on our board. The board I'm building consist of 9 BGAs, all of them are OK except for one, intermittently the tester will prompt no-contact message. It's happened on a diff. I/O, but only happened on that pa

Well, the paste must be OK, because other components don�t have this problem. The board must be OK, because other components don�t have this problem. So, it must be either the component or the profile. I�d speculate that you need to do some work t

We can offer two ways. We have a process control tool for OSP boards to validate the finish......but the dates yer talking may be best to take Daves F suggestion. NOW as far as the HASL finish goes...We may have your answer. We can Chemically revers

Yes, by the component is a start. There is also board cost, and process material costs, engineering costs if needed, pallet cost if needed, and packaging costs. Inspection and test are another part of the cost. Will you provide your own test-set?

We are currently testing 0201s. We are using T3 paste, and it is working fine. You will need specialized feeders, test components, and test boards. Also depends what machines you are using - some are not capable of placing 0201 components. My s

I am planning to evaluate DEK's Formflex board support system in our plant soon. Does anyone have experiences with this? I know that the grid of pins "locks on" to a particular product after the initial setup, but am curious to know how each individu
