I used to just follow up profile development with a single pass with a MOLE, one thermocouple in air. I'd keep that profile as a baseline, and have the operators run the MOLE through prior to production and compare the results to the baseline. I foun

We have evaluated (in-house) the following machines: Agilent SP50, CyberOptics SE300, Siemens OS. We have also evaluated the MVP machine and the Orbotech machine off-site. Best bang for your buck??? CyberOptics by far! Better Gage R&R, better standa

Matte solder mask greatly reduces the potential for solder balls, and since you altered the machine parameters with no improvement it might be flux related. Do you use a VOC free (water based) or alcohol based no-clean flux? Do you use machine settin

Jay Go to the Services menu and then station configuration. Choose your F3 machine from the list. This will open the tool that allows you to configure what the machine has on it. Look to see if you have a box with the following: WPC-TR S_WPW_80F
