Soldering or welding source
Laser soldering uses a low-power diode laser to melt solder on the joint. Thirteen of fifteen listings we checked were fibre or YAG metal welders. Ask the laser type, wavelength and power range.

Search for a laser soldering machine and most results are metal laser welders, which will burn a circuit board, so first make sure the quote is for a low-power soldering station with wire feed and temperature control.

Laser soldering uses a low-power diode laser to melt solder on the joint. Thirteen of fifteen listings we checked were fibre or YAG metal welders. Ask the laser type, wavelength and power range.
A pyrometer that reads the joint and controls laser power keeps boards from scorching. None of the fifteen listings mentioned it. Ask whether it is fitted.
Wire feed, paste dispensing or solder balls. Ask which wire diameters the feeder takes and how feed is synchronised with the laser.
A closed cabinet can bring the machine to Class 1 under EN 60825-1. An open station needs a laser area and eyewear. Ask the class on the label.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

| Require this | A pass looks like |
|---|---|
| Solder a counted batch of your joints with your wire. | Joints inspected against IPC-A-610 at your class, faults counted and recorded. |
| Log joint temperature by the pyrometer during the run. | Peak stays inside your alloy and component limits on every joint. |
| Open the cabinet door while the laser is firing. | The laser stops at once. |

A wave or selective soldering machine.
A laser welding machine, which is what most listings under this name actually are.
06
We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
07
Every machine we source in this area is on the Electronics & assembly page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
Straight answers
The laser modules can be close. Temperature control and process software differ most; test those.
The three tests above and the laser module serial against the invoice.
A Declaration of Conformity with the laser standards, a technical file and a manual in your language.
Your business if it brings the machine in: your name and address go on it.
