I've used handheld ultrasonic gages on silicone in the 4-12 mil range. A coupling agent is needed between the transducer and the material - we used DI water vs. the supplied gel. Fairly straightforward, setup is done off a reference thickness of ma

Our Fuji IP2 m/c will not recognise fiducial marks. M/c lost all proper data and without any backup documentation on what data was originally inputted I have had to use educated guesswork. Is there info that needs to be in the proper data for the IP2

We have used camera's before, mounted in suspect areas of damage, and recorded a shifts worth of work. When we found a damaged part, we found out what time the damage was found, then looked around that time frame on the camera. It can be complicate

HI, i work for an EMS company and i got a few remarks on the solder mask question. In the manufacturing of PCBs there should be no difference if they use other color solder mask, but in the production of electronic assembly it could make a difference

konrad, why did you change your mind now? Now you can agree with PCB manifacturerers? I didn;t hear anything in their defense and you gave up. If colour is not the same each time, that means they don't have standarts or knowledge to control it, an
