Hello Everyone, Does anyone have any experience with an SMT right angle LED from Panasonic, part number LNJ123W8PRZ. In our experience the pattern design from the vendor was not very effective (the part swam around on the pads & flipped backwards dur

these components generally have flattened through hole leads that have been formed for SMT, I have found that they do not sit well on PCBs. They rock, the leads are sometimes angled, etc.... In addition to Robs good advice you may want to just be sur

So it's a C-n-C clearance issue? Could you go with the other cutnclinch unit...which ever you have, get the other one (one's right angled, one's offset at 45�)? Yeah, I know, they're not cheap. Other than that, hand place some of the SMT in chip bon

Hi SMT Engr With a double-header connector do you mean Double Level Right Angled Header Connector. If so there is a big difference in heat sinking capacity between the two rows, as where the pins of the top connector absorbes twice as much heat as t

We are using a right-angle SMT power connector on a board. The connector has 4 leads and two board alignment pins. The layout for the board is such that 1 of the leads is not used and the pad for the lead is not connected to anything, not even grou

Defining failure modes will help determine what you need to quantify in all processes. Personally I wouldn't pursue the DoE angle (varying setup parameters to determine robustness). 1)How about % pad coverage, paste thickness, and accuracy? Define w

Oh dear, I tried not to respond but i couldn't help myself. Stop me if I go off into the woods. My guess, Chris, based on your fleeting reference to GF files, is that your SMT machines are Siemens Siplace. If this is so then package orientation def

Thank you all for your advice. You are right this is two sides board, and dropped parts are on bottom side, and it is refered just to very light switches. I am using same temperature setup for top and bottom. What is interesting I am manufacturing t
