I have used tooling holes and fiucial registration since the late '80's. In fact if your maximum "vision" tolerance is +/- 0.05mm, your in the same ball-park as locating pins. It is true that fiducial registration is more accurate. However, I woul

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

Ken, Thanks for the feedback. Unfortunately (or fortunately) I am in Mexico and we make our own PCBs. That is another conversation entirely and another of my fix-it projects but currently we drill the PCBs and align the artwork to the holes visually

If the goal is selective soldering (not to raise the substrate temperature too high), consider the use of microwaves. Our company has been working on this technology for selectively bonding substrates. For example, we use the process to bond ROHS met

Yes, PROMATION has customer's using laser to solder PCBs. This is too broad of a forum to discuss openly so please feel free to write me at: Gary_Goldberg@pro-mation-inc.com Perhaps I can assist Gary

Is anyone using a laser to selectively solder components to a board? I'm just starting to research selective soldering methods for the company i work for as we're looking to replace our current hand soldering processes for lead- and lead free- produ

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

Why not use tooling pins (locating pins)? Sounds like the same accuracy...

We have a Yamaha GEM and the laser will not recognise components. The laser has been changed in the past by another engineer, but this failed to rectify the problem. Can anyone advise how to test the laser or use some machine diagnostics so that I

Many years ago I remember the Philips CSM series SMT machines used a small tubular laser system for identifying fiducials on the PCB. Can anyone suggest suppliers for these devices. Thanks.
