Wait...stop! Some adhesives will void when cured... some common branks... maybe already mentioned. Heraeus PD955 will minimize voiding when curing the adhesive. Voiding can have devestating consequences....learned from experience. Another key is kee

If you can, put a pressure tank near the machine. It will help stabalize the air pressure, but only if the compressor is providing enough air in the first place. Throughhole PNP machines tend to take air in big gulps making the pressure go up and dow

are you sure it isnt down to an hygroscopic contaminant causing the problem.I've only ever seen it once or twice in gold,really quite unusual.Its not too much gold brightner or similar residue.If it can be cleaned off then it shouldnt be there so it

The dedicated fixture never really wears-out. You may need to change tooling pins and hold-down tabs, but it will still be accurate when we are all long gone. The adjustable fixtures seem to wear-out. Depending on usage and care it may go from 3 y

I think you can reach that screen with SH SET command, then do a SET [command name] [value] to change it. Make sure you write down the original values somewhere or do a print screen of your current settings before tweaking them, though.

I assume your vacuum suction is good. Is this an above mounted board stop sensor? -Make sure it is finding the correct fiducial and not a similar object nearby. -Try physically moving the X-axis to check for backlash. There should be no movement.

I presume you are looking at low melting point solders. Firstly, I would consider running BOTH sides with the same paste - this will cut down the opportunities for a mix up with rework or retro-fit. Secondly, check that there is a cored wire availabl

Ms. Chunks, You are correct nobody mentioned anything about RoHS. And, right or wrong, our quality department's official stance is that "the only thing about RoHS we have to be concerned about in our industry is Pb". It is not just our quality dep

I have had the Amistar LP1000 for about 5 years and LOVE it. A little trouble between the Zebra printer and machine but since I bought it used no pay no upgrades and I understand new software might improve that. Otherwise it always works. Probably pu

But don't you need to control the rate of the drop in pressure? I'd think if you pull down quickly it just results in the same popcorning you'd see in a reflow oven. I just know it's not hard to boil water in a vacuum chamber. For that matter, it's
