I would agree with JAX for a general estimate. If you have a few specific boards Universal can put them in a simulator and give you pretty close estimates. I would reccomend you go to thier NY facility and actually run some boards and get to know the

Hi Mark, I'm guessing from your letter that you are not asking about traces, just component values. We use a tool called 'smart tweezers' (catchy, eh?) to do jsut what you are asking. Very easy for our QA department to use a BOM to compare agains

Good day, I worked with Maratnz some time ago. My own opinion is that this is limited machine with limited functions. Main disadvantages are: - Rather costly, something about 100 KEUR per table top machine; - 2D scanning system (direct light module

Pete's advice is spot on - you need to do this. We did roughly the same thing, and the known defect board caught a few out - especially one manufacturer that lowered all of the fault thresholds to pass the previous defect free boards (we didn't tell

Chunks, For our lead-free eval, we had the same problem with "charred looking" solder paste up the component termination of one of the smaller discretes, coupled with excessive solder balling...this smaller part did see peak temps in the 240 range -

Hi, I take it you are refering to intrusive reflow? It came around as more components became available in surface mount packages leaving mainly connectors left over for a separate insertion operation & wave/selective/hand solder. Manufacturers imp

Histroically we have designed our pcb panel configurations around the v-score format. The QA Dept of our company is is suggesting that we revert back to tab-routing as away to avoid damage to senistive components like large package ceramic capacitors

Hi, just my comment, theoretically No Clean means no Ion Contaminants from Flux, but it some some case ion contamination (Cl-Br-F) could come out from raw PCBs, from Components, from fingerprints, etc. To incorporate a ROSE step in the pro
