Kerry, Why don't you purchase a decent stencil cleaning system that will not leave behind dry solder paste rather than purchasing a machine to tell you how dirty your stencils are? For less than the cost of a stencil inspection station, one can pur

first try to get rid of the problem instead of cleaning. Try Almit V16L for finepitch (good experience!) no, I do not work for that company... assuming that the rest of your process is perfect and you do not use old paste, do not use the same paste o

180deg More important are the preheat and soakzones and temp ramps. How to check: I used to do it as follows: use a TEST-PCB with fixed thermocouples and connect it to the mole. Print the profile on transparant paper. do it again e.g. each week and

Oooo, nice machine. For chuck repair, try: Mt Sterling Industries POBox 670 Mt Sterling KY 40353 606.498.1015fax4156. This is not rocket science. A local machine shop could probably do just as nice of a job. For newer chucks, try the brokers list

I have problem about glue printing measurement ,anybody has process of glue printing . How do you measure? as I know "push test" is the method for testing the strength of connection of component and board but I don't have specification of testing for

Your point about thermosets getting soft in the preheater of the wave is well taken. But an adhesive that is used past its expiry or other up-front lack of process control represent 99 & 44/100 percent of the reason for �glued parts falling off in

Look like no way you can measure after glue printing. We have been running glue printing for about 2 years and using the "push test" method for testing the strength of connection of component and board. I don't see any problem. For component ( 0603 &

I recently purchased some magnifiers without doing much research at all and now I realize I should have come here first. The units we bought have a round lens and people are complaining that they can see in the middle of the ring but their vision get

Hi Jacob, Purchasing high quality magnifier highly depends on your budget. In my experience, rectangular lens is much better than round lens as the view area is bigger. Brightness is very important point to consider. Don�t choose white light. Otherw

Moisture would be my main concern. Even though components are plastic, they can absorb moisture. Moisture is also detrimental to the the solder itself. The water droplets that are left behind (evaporated even) could cause problems (i.e. chlorides).
