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

It's the printing part that's the most challenge, right? You can print it correctly, then you should able to run it with PnP. You might need to have one "print" fixture only for screen printing, then transfer the printed board to SMT fixtures which

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

The lock is manually being able to twist into the lock position and unlock by twisting in the opposite direction. I highly doubt that this is the real problem. First check the rings on the tool to see if they are too worn to hold in the mount head. S

I have a single-view camera on a Topaz-X machine. When I define a connector type element - it displays messages like in attached files. If I change the type to IC - no problem. There is also no problem when "learning&quot

I presume you mean at microwave frequencies. If not get it right in the CAD. Programs such as Microwave Office and VSS make it easy. Also Ansoft, Keysight Eagle etc. Having used MO and Eagle I would heartily recommend them. In the bad old days one tr

It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will

Hello, I have searched the forums for this specific topic, but can not find the clarification I would like. I am setting up a baking system to "reset" SMD components using a vacuum-bake oven. According to the JEDEC-STD-033 standard, depending on th

OK, got a lot of information today doing some testing.. Version number:- 07 SP11 (985 B02) Released Dec 8 2006 I did the tool(less) calibration of the squeegee height, which worked fine, no error. Did a test print, as you can see from the image, t
