Smallsmt:



I like to show some new working videos.

l0wside:
Looking at the first video, I wonder if the machine or the paste printing makes the placement of the discretes as bad as it is. See attached images (stills at 1:00 and 3:08), the resistors and capacitors are partially shifted, aprtially rotated. Sure, the soldering process will compensate this, but it does not look overly convincing.
Your solution to place the huge (208 pins?) TQFP is neat, but essentially a hack. Would the HP variant be able to place it without extra tooling?

Smallsmt:
Max this job runs at high speed without alignment so you receive sometimes misplaced components. You have two options to improve lower speed or use vision alignment! But this light misplaced parts will align on reflow process.

Smallsmt:
We plan a camera upgrade to do 30x30mm parts in the near future.

l0wside:
OK, so you did the small parts w/o vision, sacrificing precision for speed. Understood.
And the large TQFP is (currently) simply too large for the camera. Also understood.
