Steve, Use the 1000 as a chip shooter only (and thats if it works once you turn it on). If you have problems with the 1000 just post questions as i am one of the last guys on the planet that knows that machine (and its been a while since i have worke

This is somewhat a hard question: Have You ever concider to contact Your manufactor servive engineer?! I have been seeing a lot of "machine specific" questions here in this forum and I must wonder if this forum is to help people out when there is a n

Chris, From your email I am assuming you are using an immersion tin process. Is that correct? If so, I would highly recommend you talk to your board house about the amount of tin that is being deposited on your boards. If the tin deposit becomes ver

I need a good digital photo or two of the turret of a Siplace (or equiv) style SMD pick and place head preferably laden with die or SMD parts to explain a bulk handling concept to some machine neophytes here. I could alternatively use an image of any

We use the JBC irons with and without the "leadfree" tips. We really have not noticed much difference between the standard and the lead free. The lead free tips do last a little longer but the tips are somewhat deformed by the extra plating. As f
