Hi Ed, It all depends on more info needed. How many preheaers do you have in your wave? One, two, three? Are you talking bottom side preheat? What size boards do you run and what type of parts are on it. Typically, preheat does several things; w

Thanks for your input! Your ideas always help. The plan is to remove Captcha as part of the posting process for those members who have participated frequently. This will be in place next week. BTW, Dave can you give me any more info on Captcha no

Has your board house reviewed the PCB layer stack? Make sure that the layers are balanced in copper weight, etc? Have you tried pre-baking the boards? We just had an issue with some boards warping that have never warped before for us. It happened

The best method of cleaning misprinted boards is with a stencil cleaner. I would not recommend the use of a spray-in-air system for misprints. Spray systems can cause solder paste to become embedded into vias and under components (if double sided).

put the tubed parts on the side of the machine that is desired and then when optomizing in the condition portion set it to "feeders move within table" simply setting it to feeders move will result in the parts moving from front to rear and visa versa

There are no requirements acceptance criteria for baking of board assemblies. What are your customer requirements? The common reasons people choose to bake PCB are to prevent: * Delamination of multilayer boards * Measles, particularly on double si

I never saw in any post if your machine uses the camera to find the board edge or if your machine uses the bottom front rail mounted board stop sensor. Also is this with only one particular job you run on this machine or is this happening with ALL

Thank you- my point exactly and it starts in SMT- operators pulling the wrong paste from the fridge, touch up using the wrong solder wire, etc. My solution- GET THE LEAD OUT!!!!! I'm a CM- high mix, low to medium volumes. No steady all day every day

Yes, mostly. The computer just has a setting for which size frame it is in (66, 84 or whatever). The bearing slider is almost certainly the same, too, although the rails are a different length. As best as I can tell, my 1306/20 (which is NOT a III

Jon, I looked it up woth NSK thats the name on it. A rep had to talk to the factory and found out it's a discontinued part. simular bearing sell between $ 80.00 and $120.00 some sell as sets two bearing and one slide , some sell just bearing, NSK
