Can you install the part post-smt with no clean flux?

We have been monitoring our solder defects at post-SMT, post-Wave, etc.in our plant. I want to compare our process performance to a "bench mark" for solder defects at post-SMT. The question I have is what is the "bench mark" for soldering defects in

I'm new to all this... we have a board with one BGA blue tooth device. one test for the board is an rf test that measure successful packet transmission. we find that we get much lower error rates if we "reflow" the BGA with a heatgun. We do this

It's some time difficult to control process when using a heat gun. What is the intent of using the heat gun after test?

It would be nice, save you money, improve yield, improve reliability, etc. if your reflow process was more effective. It sounds like you're not getting the part hot enough during reflow soldering. Tell us about: * Measured temperature on this bluetoo

I agree with Iman. Verify the integrity of the component for moisture. Most definately place an amount of ownership on your PCB supplier. Request tank analysis results and copies of the lot travelers. Look specifically for any in process rework pro

Dhanashekar, Yes this is an important proces control tool. This will show if you printer setup is correct however, I put more importance on coverage. If your paste height is 1 mil shorter than it should be, you may need to look at your printer setup

I would try to panelize as big as you can for sure as you'll spend more time handling single boards than running anything. Additionally, this size is very close to smallest capabilities on GSM depending on your configuration. Fids on all boards in

We use Mirtec MV-7s for post SMT inspection of solder joints as well. The artistry is in the program debug. We are very pleased with the solder inspections provided by these machines, and technology having advanced bit, most every AOI machine has t
