It's nice that you seek a broader opinion than your own. Further, if we were your customer, we would neither care about the opinions of your other customers nor the observations of a bunch of twitchy CM engineers that you recruited from the internet

Kevin, As Steve mentioned, you could be running out of memory space - a few things to check: 1. What is the file size and how far does it get when loading the exec back on? Depending on this, you could be out of memory. 2. You may or may not need a

Thanks for the feedback. The Finetech machines look very nice, but are far out of our budget. While we are looking for the most cost effective solution, we are able to spend ~$15K on this machine. We really just need a reliable way to remove and rep

Hi. We have changed our produktion from high volume to medium/low and have to start hunting change-over time. We have a lot of products with two sides and the settings of pins in the DEK 265 and Fuji QP242 machines when running b-side takes to long t

Chunks, Nozzle unfriendly? Maybe it should be called nozzle hostile. Depending on the machine and lighting a nozzle with a 1.8mm tube might work. In English units that would be a .072 OD with a .062 ID. The area such a nozzle would pick from is the 6

Thanks Patrick, also IPC-HDBK-001 explains even better then IPC-J-STD-004, but unfortunately not yet infos about flux for L-F soldering.That's why I am trying to get some infos more from experienced people. Some L-F (SAC or SACX) cored wires vendor

The proper method is to load a flat plate into the X-Y-Z table. The plate size should be as large as the largest board you run. Indicate the entire area of the plate with a dial indicator. I don't remember the exact spec, but try to stay within .2mm.

Brian, We had similar problem in our inline wash machine time ago. We checked everythin on equipment (filters, DI water purity, sprayers angle, etc). To make the long story short, we found out that the problem was caused by a new solder paste. This s
