Jack: You should use your components promptly. Don't store 'em, only bad things will happen to them. 1 You should store all your components, not just your SMD reeled components, so they are not damaged or their solderability decreased. Check the

You have provided very little information. Two similar possibilites come to mind: poor pad solderability protection and old boards. POOR SOLDERABILITY PROTECTION: Maybe the nickel plating under the gold is oxidized, contaminated, or otherwise very

What a challenge! I think it all depends on the equipment used. Seems rereflow of BGA isn�t that good (see the advices for wavesoldering BGA populated boards). Although you might check for the tacking force by sending a sample BGA board head over thr

Hi NAMCo, I really don�t see any need in replying twice to an over 2 year old thread especially with no obvious technical content. A wrong phonenumber alone isn�t blantant and IMO no reason to open such a thread again and again ... that doesn�t help

Does anyone have an idea of what a good placement rate (pph) is for a low volume, high mix smt line? We do small lots (10-300pcs), with a feeder count that ranges from 28 to 130 per setup. We have low volume machines (an old (real old) Siemens HS-180
