Your typical high mix line would consist of, Stencil printer, 1-2 foot conveyor belt, fast PNP machine (say a universal 30 spindle turret lightning head), 1-2 foot conveyor belt, large/heavy part PNP (say a universal flex jet 7 spindle or 4 Spindle),

At first glance you would think so. But just as in real life manufacturing, EVERY problem can be solder related. Naturally the problems with broken parts, wrong parts, parts made wrong etc... are generally found right ways, so no one really posts t

There are so many variables to this. It could be paste, pad size, contaminated components-pads, placement speed, component thickness being wrong in the program, dropping parts into the paste instead of placing them, component recognition ploblems. Is

You might want to check the components as well, I've seen a similar problem with re-balled parts using the wrong diameter ball. that would also contribute to added solder. good luck

Hi mates, need some help to resolve a thumb-twine situation. As a high-mix, low volume prototype build house, we always conduct a first article inspection (FAI) on every model setup conversion in the SMT production Lot run. we do this FAI by mounti

Hi again, yes you have to pick the laser level sometimes. The machine will put some default level based on the component dimensions, which sometimes will be wrong for your part. Unfortunately it has been awhile since I worked with Juki so I can't te

Doug, What I've done in past was calling them as 1206T.5, 1206T1.0, SOIC16, RESNET16, SOIC16T5.0, ALCAP4, ALCAP5 etc. T means thickness but for the ALCAP case 4 means 4mm diameter. If you have the time and patience, having a board and attaching a s

One of the points brought forward on this discussion is the level of responsibility the management wants to give the operators. The more responsabilities = higher salary.therefore, in order to save money in salaries, the operators are not held accoun

The software is crazy expensive for some of this stuff and in many cases you could develop the bits of it you actually use in-house for a fraction of the cost. Unless you are a company who really like this level of process control and you run multip
