Ken is not of this World! His equipment and "Programming Team" is perfect. The rest of the world uses "sticky" boards when programming. "ALL" the big guys...Panasonic, Fuji...etc suggest using the "sticky" method beofre running any production boar

I agree with the comments below. I see no difference with lead free. Across five reflow ovens our external nitrogen tank was about 14' tall and 7' round. I am with a different company now due to the great ole american "lets send product out of the co

Does anybody have any experience or knowledge of processing PCB assemblies featuring pyroelectric sensor devices, the type used in Passive Infra-Red Sensor modules? Since these devices are, by definition, very sensitive to heat, how do you get round

Gents, We've been using a round 1:1 aperture for a 5 mils thickness on our stencil design on 0402 and recently, IPC guidelines recommend oblong, homeplate or reverse homeplate. I believed the PCB pad for 0402's area within the recommended size/dimen

We can't tell much from your pictures, except there are rounded gray blobs that could be solder. If that's the case, you need to get that solder hotter. Please give us the temperature readings of those blobs during reflow. You mentioned that you're

Hi all, it has been a bit of a delay but I've finally had a chance to do some further investigation on this. First off, we spend some time to clean the solder bath using Kester Solder Saver and scooped out a lot of crap. We then added about 5kg of

You will need to develop your reflow profile which includes drilling a hole through the fab and into the ball for accurate temp measure. During profile/process development you will probably want 3D x-ray (consider contracting that out). Once in prod

I've gone round and round on this very subject with our manufacturing engineer. He prefers to use panel fiducials and I prefer board fids. I've seen the result in placement from bowed PCB's in the machine. Skewing the board a fraction will throw off
