Dave's estimation is pretty conservative but there is a lot of equipment out there and a lot of people happy to make a sale.Implementing both mentioned processes it's difficult and time consuming .Even if you get good training from whoever sells you

This should be a fun one! I was asked the question from our Engineering, should we use die attach with wire bond or go ahead into the new world of flip chips? Right now, I am faced with information overload about the two processes but I am really l

Hi, we do Sn plated I/O pinning insertion into Ni/Au thru' holes. no problems here so far, as we cater for the "interference" (fit-allowances) of the I/O pin into the thru' diameter, via improved PCB thru' hole designs. before this cater/considerati

What do you mean when you say "structure"? Taking a different tact to get at an answer to the original question, if applications such as general, BGA attach, and die attach inspection require a resolution of 10 units. What would you suggest are the

| | I have some 1.25 mils Al wire bonding chip on board process. After epxoy-based encapsulation, I do some aging test. How can I "see" or prove that there is a "wire break" exist due to the tension of thermal cycling? How can I know the failure is c
