We have been using Cree 3 color LED's (CLV6A-FKB) in many products for several years (pic attached). At the rate of 3 to 5% of the units assembled with this LED, the Red LED fails. After touch up with soldering iron it functions. This happens to the

We've been getting more and more flex and rigid-flex assemblies. Making carriers for mounting the boards to go through printer and pick & place is becoming more challenging with the size of some of the arrays. Normally we use a pair of pins tha

Yo Ho! I'm a little late to the party, sorry! Flex can be a simple PCB to process through Screen, Pick & Place & Reflow, if the card is designed properly. 4 symmetrical tooling holes .125" diameter and 5mm in on each corner of the card. Wedge Effect:

Very late but here's my 2 cents. Will require a custom fixture for every flex or semi-rigid flex. Depending on panel thickness; use 2 tooling hole to fixture on one axis, other tooling holes will have pullers to ensure proper placement. Even with the

You should be able to see the counts in the service screen for the motors while testing them...that's usually the easiest way to see if they're functioning...at least the encoders. In some of the older systems, the drive motors were all the same, an

There's a place for both methods, but the advancements made year on year in 3D printing technology and quality give it the edge I reckon. We use 3D printing a lot and do it 'in house'. There's very little waste compared to machining a part from a bl

Hello Pak Agus, Was there perhaps a change in solder paste? There has been confirmed occurrence in your case which happened in the work place I was before; all same parameter, equipment, material, and suddenly solder ball outbreak happened across al

Hi, my company bough second hand pick and place as our second machine. After first transport after start just when initializing, It's showing problem with Z calibration. After second position setup and connect again after month, now showing &

Key benefits for us: Labour saving - machine part of SMT line (mainly one product type, 2 shifts), so boards effectively delivered ready for the next stage, with no human interaction. Uniformity of finish - where we had a critical dimension we run

We had a custom bar code storage and feeder setup. Stores material handlers would bring the parts to the line, scan the part number on the kanban card (always accompanied the parts), and the storage location LED flashed so they knew where the place
