You are right about the very poor support for smaller customers. I had told them we were looking for another paste and now they have sent the reginal manager and the US sales manager has come by to see what they can do for us. All they keep saying is

Glue has different mechanical, thermal, and electrical properties than solder. That's why all these very nice no-lead people are furiously trying to gin-up some wacky solder alloy, rather than using glue. Among the papers in the SMTA Knowledge base

Dreamy, OA fluxes / pastes have differing levels of activity. Most OA fluxes must be cleaned very soon after reflow. OA fluxes and pastes, while offering an aggressive flux package and a relatively easy removal (solubility in water), they are the

Hi Dreamsniper, It seen this is the major issue had been occurs you.( We had face all this issue last time too) We had done a lot of areospace products before and most of ours products is a must on class 3 spec. BGA is not that tough t

Hello Everyone, I am having a pin chain speed problem. The speed of the chain will slow down after start up of the oven. Example if you set the conveyer to run at 41 in/min, as the oven warms up of conveyer will slow down phycally but won't chan

A couple of questions for You. How old is this oven? Does it have a history of problems? When I have seen speed variations with our Omniflow 7s it is usualy the encoder but it usually spikes rather hard in one spot. You can see this physically and by

Our conformal coat area has recently requested changes to our bare board houses to perform a pumice scrub operation on the PWB prior to HASL plating and delivery to us. Our first lot received caused us to have void faults under multiple component ty

Hi everyone, Our QC manager is bugging me about calibrating the TC readings on our reflow ovens. I keep telling him that doing a regular reflow profiling with a mole is sufficient to see if the oven temperature are normal. The manuals state that TC c

Ken, thanks for your answer, it is much better presented than what I was fed by our qc. By "calibrating TCs" I meant the readings the controller is displaying on the screen. So that would be the converter that we would check and calibrate. Thank you

Best recommendation is to compare the two machines with your boards and stencils. Either vendor should be able to arrange for a �test drive� at one of their demonstration facilities or at a local friendly customer. I�m afraid that your request for �o
