Yes you can open the tolerance, and that’ll usually work for a bit. Is the LAE is linked to multiple parts? If so, then the easiest thing is to open the tolerance. If not, that’ll require another route to try. Is it happening to all of the components

Our Stencil Mask Fiducial vanishes from black color to light where our Screenprint machine unable to detect fiducial during batch teaching (auto set-up alignment). Does anybody here encounter the same problem? I am searching for a dark marker or any

So what your telling me is kind of vague. Does the machine home and go to the front left corner of the machine? If it does....this could be a quad align problem....meaning dirt on the lens or so-forth. You should watch the heads homing in the z-axi

If the nozzle gets changed properly but the machine still gives the sensor, then the FNC nozzle detection sensor needs to be adjusted. It is a set of 2 sensors on a plate on the either side of the FNC. If the nozzle is not changed successfully and ge

I am trying to figure out how to teach the position of the tooling so that its aligned to the hole in the worknest. In other words...the carousel is out of position. When i go into machine calibration and i step through it the process freezes at a st

Hi Prem, OK... Is it definitely ok before the oven, as it's a big part to move. Never had an issue with them. Has the part got the correct z height on or is the paste being displaced on placement What machine are you placing it with (is it laser

Hi Prem, it will really help if you provide more pictures and metrics. Pad layout, part datasheet, stencil design and most of all picture of the misplaced part on the board. This looks like a very interesting case and I am willing to help you, but t

We’ve done similar projects. FR-811 with camera system for alignment. More cost effective than split vision. Bottom heat uses solid surface for contact heating similar to heating microwave module chassis. Our rep can arrange a demo if you haven’t

We just apply tacky flux to the surrounding components and to the bottom side components under the BGA. This will prevent cold solder if any solder joints reach reflow temperature the surface tension will keep them aligned and in place. If you nee

Cyberoptics cameras and laser alignment systems are very popular and used in a lot of machines. So weird, but there is absolutely no technical information available and even in the company's web site they don't exist. Some models like the Hawkeye cam
