What about dispensing SMT epoxy (cures at much lower temperatures, than solder reflow), p+p components, run through the oven to cure, and using a laser selective solder robot to solder the pads?

We did the trial by dispensing (both the thermal & the electrical), but in production I would definitely use a stencil for the Conductive adhesive, as the shape, spread & volume of the adhesive is critical. (No wicking or spread) We also looked at

There are factors that manufacturers have taken into consideration when dealing with coating. On/off times, dispense speeds, heights, etc.. Dedicated software with tools to easily map out paths are a godsend. We made our own coating machine with a s

You could talk to someone like Zebra labels about traceability using all the latest buzzword technology like IoT, RFID, NFC etc. Traceability will underpin many automated tasks, several elements of your SMT line can also dispense/read labels so you c

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.

We're about to setup our own soldering process... I have some experience from the contract manuf industry. Types of solder processes: - tip soldering robot for low volume - Japan UNIX LASER soldering machine for high volume Questions: 1) Examples

Wow, you're using the Surface Mount Adhesive for mechanical vibration? I've never heard of SMT adhesive being used for things other than holding the components in place before wave solder. Does it work for mechanical purposes? Glue/Wave is a proce

We have a PCB rework dilemma involving a reflow profile. This is a SAC305/Low Solids (aka no clean) process where we are currently hand soldering (5) components that were DNP. The boards have an acrylic coating and we take off the acrylic at the par
