I agree with DDave, You have something else wrong! .100 dips with .05" lead protrusion should not bridge (in fact I would think that it would be almost impossible). Tell us about your machine, (laminar flow, A-wave, etc.., size of nozzle, wave heig

I need some input on what good solder thieves dimensions should be. I am limited to solving my bridging problem with solder thieves; all process/wave variables have been adjusted to try to solve this problem. There are several of these connectors on

Various solder metal supplies sell pre-forms as loose individual shapes, usually donuts. The loose performs then are placed on the connector leads. If you have any volume at all, you would want to look at a �shake table� that would vibrate a batch of

I am looking for some design guidelines (length, width, spacing) for solder thieves which are placed behind trailing pins of wave soldered SOICs. I'd appreciate it if some one could direct me to the appropropriate reference. Also, has any one perform

Bridges are front to back. To me this seems to indicate thieves would pull the solder away from the pins. I feel I am correct in that theory. Yes, it would be a good idea for us to bring in a consultant but I have the opportunity right now to make b

Given that you are bridging front to back, contast the situation with the thiefs used to prevent bridging when wave soldering SOIC. If this is reasonable, the thiefs should be located behind the trailing connector pins. You can prove-out this [and

Tell us more about the location of the bridging [ie, front-to-back, back-to-back, front-to-front, etc]. Thoughts are: * Your annular ring around the hole seems large. You have 0.007", consider 0.003" to be the minimum. Your board fabricator can gi

Hi Good Luck, I worked a long time with THT components like you discuss and boards totally or partially populated. Dee Machines, Electroverts, Hollis and an other and never had the kind of problems you are listing stayed with us forever. I mean you

The design rules for solder thiefs are that the extra pads must be bigger than the proceeding pads to be worth while as a minimum guide the pad is 3x the size of the proceeding pad so if the pad is 0.030" the thief would be 0.090" wide. As steve has
