Could you make up your own adaptor cable to connect to your programmer, then fit a small form connector like a Firewire on the edge of the PCB? It should only take up about 7x7mm of real estate as opposed to a 2.54mm 5x2 pin header 12.7 x 5.08, or a

*UPDATE* I decided to modify the experiment slightly by forgoing my attempt to achieve reflow with the component. Instead I applied SN42 paste directly to the pad and attempted reflow of the paste by itself. The end result is as follows: Hotplate

How can I upload image to this forum? I can show you the pad layout. I am thinking maybe too much solder. I used 0.16mm thick stencil but notice many us 0.12mm thickness. Also, cream layer is 100% of pad surface, I know for fine pitch parts it is r

I have the situation where we may need to use a variety of reflow temperatures. It seems that the design engineers want us to try a variety of "unspecified" pastes on the products. For example, the first PCB would be assembled using a higher temperat

I knew this would happen. Someone wants to rework a bad BGA artwork by cutting a trace and adding a wire under a 292p 1.27mm pitch PBGA. Has anyone done this before? What kind AND size wire do you use? How do you hold it in place during the replc

| We are changing from through-hole to SMT, wondering what pitch requirements would an 8 pin SOAC require for pick and place? We think that this would be our finest pitch part. | John: Never heard of an "SOAC." SO packages are 50 ptch (50 mil, 1

| I have a mixed technology board ranging from 50 mil pitch devices to 20mil Qfp's to PBGA-352 at 1.27mm, and 6 Intel uBGA-48 at 30 mil pitch. With all these different package types i'm torn between using a 4 or 5mil thick stencil. The ball dia. is 1
