We have had soldering problems with fine pitch QFP in the past [and probably will in the future]. Several questions leap to mind: * When you took your profile on the component pads, do you profile on the pads that did not solder well? * When you say

Comments are: * Some people use calibrated boards and components to remove sources of variation when using their CMM to measure placement accuracy. Sources of supply are listed in the fine SMTnet Archives. * It�s unclear that a single board will mee

Hello Armin, If you are putting a matrix together to determine the best equipment set to use then a good path would be to start with your product and production expectations. Is this to be utilized strictly for typical SMT products? Are there any

Average people get on stage and sing cover songs in karaoke. But for other people, people in the karaoke circuit, it's a money sport. As with other bar sports (ie, pool, darts, horse, etc), the karaoke-for-money game is rife with hustlers. * "In 'D
