50% chance his boss has heard of (or maybe even one time seen) delamination and wants to be sure they don't have that problem. His boss probably felt a need to specify a test and that was one he had heard of. Personally I would recomend find a way f

Most ovens I know use oil to lubricate conveyor chain, not grease. Anyway, is this what you're using: NMG No Melt Grease NLGI 2 (operates from -20�C to +270�C) NMG is a long-fibred highly adhesive grease which does not melt or drip at high temperat

I ran a profile on a dummy board with no parts and the peak temp is 220. The 220 is just the temperature of the board of course. With that BGA on it, I am pretty sure it sucks up alot of the heat. Also I am looking at the profile and notice that i

Guys I hope you will be able to help. I asked our local Fuji agent for a copy of the calculator for inputing the average deviation values and they wont give me a copy too scared we get to know too much, the ironic thing is I had my own copy but my ha

If you are talking about smt components I'd say absolutely not. If these are through hole components I'd say possibly (if they are in rows, and not a whole lot of them). The machine is slow, but the quality is great. Creating a wave profile takes abo

I do not have a ERSA Versaflow but do have some ERSA equipment. Only can tell you I will most likely not purchase anything else from them. The experience I have with their service after the sale would have to be rated VERY low. In addition, they emai

Agreed - D.I. a must. Also, operators will have to pay attention to lesser stencil life than no-clean paste. Product specs. might say the stencil life is similar but experience has showed us that no-clean last much longer and rolls for a longer tim

The answer for us at my previous employer was water soluble flux. Wash the board, no residue. If you're not set up to wash (needing a washer, DI water source, waste treatment, ventilation, etc.) it can be expensive and space consuming. Do some resea

Check the dimensions of the components in question with a caliper and put the correct numbers in Your part data. Check that the correct nozzle is being used. Also make sure that you have the right pcb height in Your program. This is somewhat criti

Try vision type 12 for capacitors, this will give you much better acceptance in the vision inspection, since those are slightly rounded. Resistors works normally fine with vision type 10. If you have a component that is very hard to get pass the visi
