These ovens maintain good profiling as long as you stay on top of maintenance. I had 4 150's and 1 125. The biggest headache is keep the plenums cleaned (very messy). Also the blower motors have been replaced a few times on them as well. If I were yo

= 0.66 aperture opening to the stencil wall has been shown to provide the best transfer efficiency and repeatability of the deposited paste. Values from 0.66 to 0.8 insure a good paste release from the stencil. The biggest impact on area ratio is the

Russ: You're correct, running second side SMDs on the wave without adhesives is more fun than a lot of people think. Ta. Dave F

Hi. Smtguys I need help. The delamination of smd (QFP) occured when we checked with the SEM. This device have been excursed smt process after baking for 24 hour (125��) in oven. Are there any other reasion in SMD delamination except humidit

Does anyone have a recommendation for a cleaning solution used in an ultrasonic cleaner for cleaning RMA solder paste off stencils and adhesive off pcb boards. I am going to be evaluating Armakleen 2001, Zestron Vigon SC 200, and Aqueous Technologies

Sounds like you are running your conveyor too fast. Check your profile and see if your board is getting hot enough "max 125c on topside prior to hitting the wave. If so then slow it down, if not then increase your preheats and slow it down.

I have heard about the new Sony SMT chip shooter. In China, It has one purchased 3 of the Sony Chip shooters. From what I heard. It is not really that good especially the vision system. ?The overall rating is just average. But the price is very attra

| A user of one of our components exceeded the floor life of some plastic BGA components. They did do a pre-bake prior to SMT reflow but only 72 hrs at 40C and not the recommended 12 hours at 125C. I've recommended accoustic microscopy to look for po

While trying to sell me a low temperature baking system for SMDs the salesman mentioned that the 125C for 24hr bake had been known to cause co-planarity defects. I thought I'd ask some experts. Any help guys?
