The only way you will be able to measure it is to count the reel before you put it on the machine, count them when they come off and deduct the amount expected to be placed. you will then have the result of attrition on the machine. or.. Pick the p

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

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

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

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

Hi Danial, Yes, you can use one cleaning chemistry for all paste types. There are many available chemistries from many manufacturers. The chemistries that I would recommend include: StencilWash Plus from Aqueous Technologies http://www.aqueouste

Probably of no help but here it is anyway This is a tuff one. Attrition is due to many factors. You have machine rejects (visual fail, no pick), feeder set-up loss each time a reel is removed you lose X number of parts depending on feeder design (w
