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 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

Hi, I just set one of these up a month or so ago, so it's all pretty fresh. The 265s have a pressure sensor amplifier box that needs calibration using the OEM calibration jig. OR you can use a 3 quid digital luggage scale from Ebay. The calibratio
Electronics Forum | Sat Nov 09 19:35:25 EST 2019 | richardcargill
the issue is the calibration. What you set it for has to match what it actually reads or you get the error screen at the end of every pass. If you go into the maintenance menu ( using the key next to the system button ) you can check that the pressu

Yeah, sorry, just noticed that bit on the photo. I'll have to have a look at my machine on Monday to see if there's anything that might explain it. The pressure system is pretty much the same on all the 265 variants so if you can find a service manua
