You need to decide what types of processes you need to run right now. What is the mix of different devices and what volume is required for each product. Are you doing a mixed technology board (SMT & PTH) or just SMT. Are there fine pitch devices (und

In production,we are seeing high defect for Hair Line Solder Shorts for PTH connector and the Hair Line is too tiny that X-Ray and ICT could not detect.Any suggestion on how we can resolve or at least detect this upfront.

The biggest problem I am having is the X-Ray and ICT could not detect this shorts.ICT could not detect because onboard measurement shows Zero even without the Hair line shorts.With Hairline there is no difference in the impedance value for ICT to fai

What kind of wave are you using? Is this an old job and a new problem? Sounds like dross shorting to me, Make sure the wave is flowing over the back plate (at least when the board hits it). good luck, pr

All possible causes aside, how can a dead short pass your ICT unless the connector is not probed.

We use both technologies and each comes with a mixed bag. What is the driving force behind your desire to convert? Is it just bad chips or something else? It sounds like you are having quality issues with your vendor and you would be good to addre

What is the pitch of the device and what type of flux are you using? You may eridicate the fault by using a more active flux. I assume you are flowsoldering the device as opposed to paste in hole. Do you have an air knife? If so, you could tr
