This problem exists at a very low level but happens on all our discrete components, all our products and in two plants. Between the PCB land and the component termination there is a barrier of flux residue, this actually lifts the component slightly

Issue: At 60'C test PCB Fails. Operator did simulation. Use of Heat Gun to heat up the BGA to 60'C while PCB is powered and running. At 60'C BGA fails. When pressed system is back which means that something becomes open. Sent BGA for SEM and found t

Don't have any graphics but they are relatively simple. 1. They do need to be put into the copper. 2. We usually use a 1mm circle but many other shapes and sizes are useable but I know that all machine will take a circle. 3. Maintain a keepout area

Nope actually the whole bluetooth component is a raw part comprising of BGA and chip components in one small PCB wherein this whole assembly is encased in a shield. So basically when we recieve the part we can only see the shield and some minor chi

1. What are we talking about: pcb:s or pcba:s? 2. What exactly do you want to attain with this board test? 3. Are you a pcb manufactor or a pcba manufactor? 4. You did not mention what type of boards you want to test? 5. Mechanical, operating enviro

Dave, I have read an article by Vern Solberg who said that Electro plating Ni/Au in not recommended for PCB's. I have tried his email but get bounce back. Do you know him or his email? I knows its a long shot to ask you, but it never hurts to ask...

Anyone have problems wave soldering white tin finish? We are an ems and our customer provides us the pcb's. SMT and TH components on the board. SMT is fine but when we wave solder, wetting to top side is very poor (solder only flows half way up). We

About SACX307 for wave you can read at post: http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=38727 As I have heard, in Europe, Germany in particular, several assemblers are using SN100C for wave (also HASL) with success since years ago.
