We have encountered what appears to be mask discoloration after wave soldering. The areas of concern coincide with the areas that were exposed selectively by fixtures during wave soldering, dominated by one date code of PCB with a slightly different

Hi Stephen! The nozzle change happens at a much slower speed to what it runs at during pick and place. They are a great machine...when everything works on them ;-) I tried sending through the proper data again and rebooted the machine. A interest

Batch Ovens

Hi, I would be interested in the data, and I after our experience with batch convection I am quite skeptical. I would be very interested in temperature plots. What I would like to see before I ever considered a batch convection oven is how the oven

Ken, We have that same version of software and have never had this issue be a real problem. I can say that we have had the machine hang on shutdown after 8 hours of furious editing, but very few and far between. If you go to another virtual termi

Who should operate an AOI? operator or Inspector?

Electronics Forum | Thu Nov 17 13:35:36 EST 2005 | mnguyen

AOI should be operated by a machine operator. I could get a monkey to stand around pushing buttons. A machine operator job responsibilty is not to change feeders and push buttons. They have to monitor the process for missing parts, misaligned, and pa

Yes, I have been using it for 4 years now. We have the 4 axis, 3 head, 2 lines. Inspection station and ir oven. I have to say you will NOT get better support anywhere in this industry than from PVA. Their crew is top notch, always going above and bey

X7R woes

Electronics Forum | Tue Jan 03 17:14:37 EST 2006 | mariss

To recap: 1) The machines use laser centering, not mech jaw centering. 2) The X7Rs are scattered on the board, center and edges. Improper de-panelization would favor damaging the parts near the edges of the board; this is not the case. 3) Both ROH

Hello everyone! I'm new to this forum. I just got back into an SMT career after a 4 year break, and it feels good to be back. Anyways, I'm doing some maintenance work with a Fuji CP-645. It has a few problems that I am currently unable to isolate, a
