No opinion here, but each state [and probably country] regulates xray machines through a "Radiation Control Agency". For a starting point to learn more about state policies, look here: http://www.rmis.rmfamily.com/db/agencyradia.php The contact fo

Yes, we assembled a lot of QFN in the last years, but we don't have a X-ray machine by ourself, so we cant't inspect each device. This type LGA was designed on a prototyping board of our customer so we would validate our LGA reflow process and a rese

Hi Evtimov. 1. yes both part and the process are lead free/RoHS 2. I ever did X-ray, the balls shape are good and I dont see any evident of head in pillow (but my x-ray machine is not too good) Head in pillow was also my first suspect. but after 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

You would be suprised what you can see with even a simple Xray machine. The engineers upstairs wanted to see if the xray could confirm there was an open via on a thin dense board with several layers. I thought (but didn't say) no way. But with carefu

Hi, Early this year, the company I work for released its first product using PCBs with SMT assembly. These boards are relatively simple with less than 30 components, mostly 0603 size resistors and capacitors with a few SOIC and one LQFP chip. These

if do not have x-ray inspection machine, how to verify the 1st board out from the smt placer that the BGA is placed accurately onto the solder pads. the diameter of the solder ball is 1mm. could it self align during reflow?

| | Anyone know a independent PCB inspection of BGA (X-Ray). We have several test boards that need BGA inspection. | | For detailed analysis try X-Tek in Santa Clara, Ca. | 408/486-9620 | or you can rent the RTX from Glenbrook Technologies for $950

I would contact the manufacturer of your machine. X-Ray equipment isn't something you want to fool with if you don't know what your doing.

Are there any AOI of X-ray image solutions for around $150K or less? We were looking at Photon Dynamics Combo machine, as well as interfacing X-ray with pattern rec., now up in the air. Separate systems will not work for our application. Appreciat
