I have waved gold (ENIG) boards. That's a pretty hot pot at 260C, wow. I have used 245C with good results. All other parameters look OK a glance. Well, PCB temp looks a little hot too at 130C before pot. 90-100C is typical for most No-Clean flux. At

All: I'm having a rough time with one of my Mydata cameras. Specifically, the X-wagon camera. I've got no video from it, no light from it, etc. I've checked all the connections, all seems fine, but it does not work. Does anyone know where there

Dude, make sure you're not getting too hot, too quick. If the BGA "dogears" in the oven, or during a rework procedure, it'll either short, or get very strained, depending on which way the part moves, up or down. Also, bake the hell out of them, as if

I worked for a company with a Mirtec. It's a great machine. The sales guy kept going on about needing a golden board. But if you program very carefully and verify each part as you add it to the library, you don't even need a golden board. If you ha

Are you saying you can't send out boards that have been touched up or reworked, or are you saying you can't send out boards with defects on them? 100% is a great goal to shoot for but most people don't expect to achieve it. It all depends on what yo

thank you devef....My point is this....If you solder all the areas that have Imm Sn on them, there wont be any whisker formation DUE TO THE IMM TIN COATING.....whiskers could still potentially form as a result of COMPONENT FINISHES and effective miti

I don't know, what you are expecting? The complete set of manuals in folders weigh a few pounds and cost very likely ~ $400 in shipping and have to be paid in advance. There are manuals on a CD in .pdf format of about 200 Mb, which I offered to send,

i would assume when the PCB planner and customer would specify what "surface layer type"they want but this section is always empty but i have found that out yesterday that we only use ENIG and not FLASH GOLD, which is good to know........ but it see

You might wanna try a small reduction in your stencil aperture. For example, for a 30-mil pad go 26-mil square aperture with 8 to 10-mil radius on your corners. Also, look at your designs. Is there enough resist between your pad and ball? Another

You may want to take a quick look at the tier one equipment suppliers. Universal and Fuji have some very competitive equipment, not sure about Panasonic and Siemens but they have to be trying to compete as well. We are low volume and never thought we
