Just thought of something while on the beach. We made a paste change several years ago when we installed another surface mount line. At around that same time, our maint. crew changed chain oil and about 2 months later changed when they oiled the ch

As the article eludes to, you still need probe access to measure the pins with TestJet. One thing I wanted to add was the use of JTAG for use with Boundary Scan. Certain devices have JTAG capability, but not all JTAG devices are Boundary Scan compa

Hey hey, A friend pointed out a nifty app, called chainr, that can be of great help when it comes to remembering setups, mapping circuits or making a "how to...". It's basically a tool to capture various forms of multimedia and link them together t

Antonio, one possibility I have seen before on BGA shorts was due to chain slippage on the reflow oven due to worn gearing, the slippage was not severe enough to move other SMT devices but was enough to disturb the molten solder under the BGA

Mike, we use a product called Dow Corning 321 dryfilm lubricant. BTU reccomends it. You can find it in Mcmaster Carr for about 21.00 a can. Mcmaster PN is 1255K14. I reccomend pulling the chain off when you are lubricating it to avoid over-spray. Th

Sorry about the non SMT post, but I figured that there might be someone with a similar experience out there. We have been having a tough time cleaning the conveyor chains in our wave solder machine. We have been cleaning them in a self cleaning oven,

Hi all We have an Omniflo 5 (-97 vintage) with pin chain conveyor. Lately the chain drive motor has started to emit some chirping noises, as if there were a bearing running dry or something. Is there some kind of maintenance schedule specified for t

Have a problem with Omniflo 5 (-97 vintage) pin chain conveyor. Occasionally the conveyor stops for a second or two, then makes a slight jerk, then stops again, makes a jerk etc. Then suddenly the problem goes away only to return next day (we switch

Good Morning SWAG, We have had similar problems with our Heller 1800 EXL's when the chains would build up oil and debris. The only way we could get them clean was to put them into a self cleaning oven and carbonize the residues. We then rinsed them
