run the board thru both backward and sideways and see what happens

One step forward, two backwards. Seems these have been discontinued.

Hi. I need to mount a LED SMD type backwards on a PCB. Currently, I am doing that manually. My questions are: Is there a SMD LED with the right package to mount that? The machines automatically place elements on a PCB, Do they could mount the L

| Seems you've taken a step backwards, or is it me? I like the new format but it seems to be loading slower. come on Jon go out and buy a new computer! Think your olde system is the problem..... Wayne

We've evaluated the Rheopump. Problems we've found are 1) cycle time differences between forward and backward print (evidently the pump charges pressure on one and not the other), 2) excessive amounts of paste left in the tubes (roughly 60 grams we

We agree with Ken. What does your field meter tell you? Taking it a step further [erzit backward?], what is it about the measurement that requires the granite surface? Wouldn't an ESD protected bench top be as flat as needed for most gauging like

We start to get mixed component leaded and lead-free, we still using leaded solder paste in the SMT process. Do you see this a problem to use leaded process 179 deg celsuis temperature reflow on RoHS compatible lead-free components with same specific

AJ, Thanks for your input, forgot to inform that there is none BGA on the PCB. I also discovered that there was another topic related mixed component that give me support enough. Will inform my supplier to perform the process in the SMT line and not

It's the same like asking wether you get a gold-contaminated solder pot when soldering ENIG boards. As long as the replenishment of dross is large compared to the intake of contaminant, the contamination level will stay within acceptable levels.

0.2% lead will make your solder non compliant with RoHS when you move to a completely RoHS compliant BOM. Check with your bar vendor how much it will take to convert a pot containing 0.2% lead to
