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

Sure. We use 9999 for our operator level security. We use a secret number [that we change periodically] for our next level of security, because we don't want people messing with our profiles. And we use an ever more secret number for our next leve

Question on Reflow Profile Development

Electronics Forum | Thu Jun 14 14:01:11 EDT 2001 | Claude_Couture

I used to associate the mass of the assembly with the reflow profile. The greater the mass, the greater the quantity of heat you need to give the assembly. Most of the time you just need to reduce the speed of travel in the oven. Try different settin

I Agree with Dave, Check spec on cap some devices have temp constraints (can exceed x degrees for more than x time or can not exceed a certain ramp rate). Check that then go through the rest of the process chances are its not your machine if no other

Cleaning stencils after printing SMD adhesives

Electronics Forum | Tue Jul 10 13:45:23 EDT 2001 | markhoch

We're stencil printing a Loctite 3614 Chipbonder adhesive, and we're using BioAct SC-10 presaturated wipes to clean the stencil after printing, without much luck. Operators are not able to remove all adhesive material left in the aperatures, and aft

It's OK to have a thin film or haze of paste left on the stencil. Printing nice bricks of paste is the important thing. Assuming you know these things, so tell us more about your situation. PRINT QUALITY: What do your paste deposits look like?

I am planning to evaluate DEK's Formflex board support system in our plant soon. Does anyone have experiences with this? I know that the grid of pins "locks on" to a particular product after the initial setup, but am curious to know how each individu

I can only describe how the Grid Lok handles component variability. The compliant caps have an annular ring that is very soft and can mold to different shapes. If a component shows up where there was no component before, the outside of the cap bend

Wudduya mean ya can�t replace that ol� John Trieber? We agree. * Waverider thingies are best used to set-up process and in machine start-up. * Monitoring product characteristics is expensive, gives little information, and is so sloooow. [Plus we tu

Blood letting on stencil printer

Electronics Forum | Tue Oct 13 09:08:54 EDT 1998 | Earl Moon

We suffered our first blood letting because of razor sharp edge clamps (DEK 265LT) and operator giving it the finger. While positioning magnetic tooling pins, one of our best slipped and really sliced off a part of his main digit. This will impact hi
