| SMTnetters: | | Does anyone know of a place where I can have some test boards made? I don't need a board with a working circuit, traces or anything like that, but a board similar to those "test boards" that you all see at the Placement Equipment

Good Afternoon, We have just comleted an in depth discussion about just this subject. We also have Mydata equipment and are facing the same problems. These are the conclusions that we came to: 1) Mydata has a formula for creating package names assu

Armin: Locating vias within the courtyard of components is bad practice. Concerns are: * Poor solder paste print quality, caused by the via preventing good stencil gasketing. * Poor component reflow, caused by the via holding the component out o

JUKI's the way to go, I feel getting one could be the saviour of a company if they want to run small & large batch sizes. Fairly quick setup times -after a bit of practice, reliability, very accurate placement of almost any component size. My lifes b

| | I am currently in the process of setting up an SMD Parts Package Database. The database will contain dimensional information to be used by the placement machinery to process parts (I.E Package Type, # of Leads, Lead dimensions, Lead pitch(s), etc

the information on "slide lines" in this forum sounds fine, but if you have to stuff 10 boards with 100 or more components a slide line is not very practical. We therefore have 1 worker do the whole board. I assume that others face the same task. Wh

It's not acceptable to us. More importantly, you need to determine if it's acceptable to your customer. Recognize that your little IPA scrub does NOT remove the OA flux residues from the board. It mearly spreads them out across the board and under c

Do you preheat the board? Do you apply on two sides and let it fill under, or along all 4 sides? Does it bleed away from the part as well, or does it wick under the part during reflow? Basically, we've never used underfill before. So I don't know

Electrically testing components is an age-old practice of the past. True "world class manufacturers" like to minimize, or even eliminate incoming inspection of ANYTHING - the theory being....a world class manufacturer should have such awesome relati
