We return materials to stock all the time. Have also noticed some repair people like to pilver the reject bin every so often so they have a stock pile of their own. This too adds up on discretes.

Are you seeing many of the components in the reject bin of the machine? If it is feeder related I would expect to see some rejects unless the part is jumping and landing in the same orientation i.e. 3 leads on same side everytime! Other than that I

The reject rate of yours could be a number of reasons. 1. Which component types are rejected? 2. From a particular nozzle? 3. If the rejected part will be dropped on the reject belt or reject bin; it suggests that there is a problem with the componen

I now have the opportunity to work on the MVII's. And I have some questions Do the PCB's have to have tooling holes for the transport of Boards in and out of the machine? These machines are running like S___t. Lots of parts in the reject bin, and s

What kind/brand of machine are we talking about? Are the missing parts randomly distributed or are specific to a feeder/placement/pattern? Does your machine remember where to resume placement if you reset it in the middle of a pattern placement? We h

Tried and True is counting your components if there is any indication of loss... this is a great TOPIC... unfortunately there are many ways to lose components. Feeder setup,problems with a feeder while in the machine(IE mylar problems or wrong step)

This may be a really silly question but does anyone pick up and hand place the reject parts from the scrap bins of the machine? My attrition rates are out of control and i think this would not only highlight the problem but also save oodles of money

I was dreaming about a real easy to use assembly machine. The software was written for operators and did not require more than a few hours training. Machine operations and board programming was written in clear language, icons, pictures and machine e

Greg This is one of the eternal questions. I have racked my brains over this one in many organisations. If you are a low volume user (as your run size of 100 to 1000 would indicate) then you are likely to loose more taped components from loading and

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),
