Hi frank, At first we did see some issue with moving the boards. We placed the AOI�s in as central location as we could. Basic we do first articles and sample QC�s from the less critical locations like paste inception and TH. And then run 100% QC o

It depends on your product requirements. I have seen aluminium wire bonding operations in as high as class 100K clean rooms. These are the assembly areas for calculators. The best is class 10K clean room for wire bonding. You can go upto fine pitch w

About $60K for a good bench-top unit and $120K for a good in-line. AOI is justified if you are spending a lot of time ($$) visually inspecting your boards. AOI machine is faster and more reliable than a human for this task. Plus, visual inspectors d

Hello all!! I currently have this thought, of maybe producing my very own type of feeders. Say juki,panasonics,etc. but building,design,and production of my own. What would be preventing me from doing so? Let's say i wanted to build a Fuji CP-4 feed

After profiling with a scrap board of the product I'm profiling, I would immediately send the MOLE through with one thermocouple only, no board, to provide a standard that I could reproduce without depending on scrap boards. I used that setup before

when we run a pilot run it usually takes a lot of time because it needs to be properly adjusted so that on production time everything could be set up easily and run smoothly. on a no feeder situation, components for the next model should be already l

Sorry to hear of your problems with your VPI-1000. As most people know the VPI line was transfered over to the Easy Braid Company last July. With most changes of this type there can be some initial confusion and and unneccessary stress placed on endu

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
