Well, there seems to be many opinions, many of which could be correct, however... With the proper laser they can be quite good for soldering. Here are a few guidelines I would like to suggest. 1) Have your product soldered first (by the vendor) 2) T

Ken, You'd think so but the tooling pins only register to the drilling process for the PCB. The fiducial registers to the copper pattern and for both glueing and placing SMT components the pads are more important than the holes. That's why the machi

We have an AUREL CS1222 machine to measure the thickness of the solder paste deposited on a bare board by a stencil printer. This device has a laser beam that has to be put on the pad where you want to measure the solder paste thickness. The measure

OK, with my masterful powers of deduction, I have been able to resolve the problem. Upon further investigation, it became apparent that the issue was restricted to those components that had the laser alignment level in the component data set to -0.2

There is a stencil cutting machine in the industry which utilizes a water jet to deliver a Laser beam for cutting stencils. There are no machines of this type in the states. The quality is no better than a Laser cut stencil using a good Laser System.

Function 30 reads CENTER 1024 RUN OUT 0.0 with any nozzle and without nozzle at all. However I see that nozzle tip stops in front of laser beam. When I interrupt the beam with a piece of paper during Function 30, Z axis travels down until I take it

Nate, If your stencil vendor has laser-cutting capabilities, they should be able to burn in your fiducial locations. This process involves re-setting the focus of the laser beam to burn the locations 1-3 mils into the surface (as opposed to 1/2 cut

Rob is right, you do need to dispense paste or pre-forms when using a laser. Although the Panasonic Soft Beam has a wire despenser. I've seen laser soldering and it does work on smaller stuff. Doesn't work well on connectors even after preheating.

Hi Karkanov, Depending on how many devices they have, you may want to go spot solder with a laser system or light beam system. This worked well on some aluminum boards we did in the past.

Operation features of many devices, machine components, instruments depend substantially on state of their surfaces. Selective surface processing by high-intensity energy beam (ion, electron, laser treatment) is one of the most perspective directions
