If there are parts "non-identifiable" then you don't know their cost. Parts under a certain cost you don't worry about. That leaves only category "A" parts to concern yourself with. Know your attrition rates especially for parts over a certain cos

Thanks for your replies guys, i definately will look into the retapeding option as on further inspection of the line yesterday i found that some of the reels have a crappy plastic on top of them that our feeder literally just pulls off, exposing lots

I�m unclear about � "BB training"??? "BB candidates"? Is BB [Box-??] [Bhote-??] a Design Of Experiments technique like Taguchi? As a start, the following affect the "attrition rate": * Assembly machine program * Machine calibration and maintenan

Russ Exactly what i was looking for! I spoke to the operators of the machine who said it does record the reject rate, but it hasn't been reset since the machine has been in there so that's pretty useless, although there's a couple of boards going do

K, aim to prevent return of rejected components back into stores. Consider potential damage caused through handling post pick and the effect of your product quality in using these components in the future. The best place to address this problem is a

Hi - I am trying to set up a visual display of the component attrition rate from our Siemens P&P Machines. There is OIS SW running on each machine so we can query a certain amount locally at each machine. Is there a way of having a more userfriendly

Those Panasonic machines should be able to tell ya pick-up rates form the feeders and shape code errors (components it doesn't recognize). You will probably get a more pick-up errors than anything else. Most of this is due to plastic tape versus pa

Hi All, I have this problem sorting out the percentage of allowance that we need (per component) for our SMT machine attrition rate. When you say 1%. Say I have a PCB with 3 types of SMD components, type X is using 30 components, type Y is using 5

We typically do not try to pick up and hand placve chip resisstors and capacitors. The risk and cost is too high for components that are a penny or less. We take into consideration that on many of our components, someone will have to test them to v
