Hi, For hand placement you should see about 150-200 ppm of errors (solder, placement, values etc) on a board populated of types such as 1206, 0805, SOT, Tantalum etc. . As for solely wrong components (component at wrong location) you can usualy redu

Regarding a Fristch semi (using tube feeders on the left side and 200 bins on a rotary belt. From working with one about 3 years ago, we found that we had an average of 240 components per hour placed versus 320 without. The difference being that you

| Greetings, | | We are discussing what should and what should not be baked and vacuum packed. Should we just concentrate on the fine pitch packages and the bga's? | What about those components which come on blister tape, should they get baked and r

I once worked for a new branch of a company. We had a board where one of two tants would shift in the oven. When I phoned up HQ because they had ran the board before as soon as I said the product name their guy said "C148 shifts in the oven" He knew

Hi,mantis, I has experienced this case.when we run a model ,misalignment and tombstone of some 0805 resistors and 1206 caps always occured.we have taken many actions,such as adjusting reflow parameter&printing parameter,checking pcb and parts soldera

Hi Harrit, We are processing SMT eleco's normally - up to around 8mm in height, the larger sizes can still be avoided and are through hole as the cost of them outweigh the benefit of surface mounting them (although we did get good results on test fo

First, why is there appears to be no marking on simple capacitors when there is a code for, yet there is markings on resistors? Attached is a interesting table, it came about after I spent hours and hours and hours looking on Internet from a 16 Volt

Hello Len. Thanks for the update, I wouldn't say we are getting the hang of it but we are progressing, I now have a vision programming guide which isn't much help when parts are failing, it just states the obvious, set up sizes etc. The light that y

Based on your knowledge and experience, could you tell me about speed differences when placing a mix of SMD at mass production? We could consider packages like the small R & C chips, then SOD323, SOT-23, SOT-23-5, SOT23-6, SON6, QFN8, SOIC-8, SOIC-16
