Laser soldering system
The non-contact
soldering revolution !
Laser soldering
Laser in soldering process is new, and Capa Electronic provides you the most advanced solution available.
Laser allow you to solder point you could'nt solder with conventional systems, and without any contact.
Top application for laser :
- CMOS sensors
- connector
- micro speackers
- CMS
Thank to a solder wire feeding that we can control, up to 0.2mm, and insure high precision and repeatibility.
The laser diode (fiber coupling type) whose output is high ( 30w) is used.
The CCD camera camera incorporater on the vertical axis onto which laser is irradied shoots an image of the target point.
Lase can also insure a better soldering quality and fastness.
The section show the difference between iron tip soldering and laser soldering. we can note differences between the 2 technologies :
- Difference of the shape, which indicate that the there was too much heat on the pad. That could decrease fastness property of soldering.
- Blacks points indicate a bad homogeneity of the solder.
Innovation
Japan Unix laser systems are leading the laser market and innovating :
Donut type lens for laser
This kind of shape for laser (patented) can use all the energy of the laser, by avoiding the center of the pad. the issue in laser soldering when the laser reaches the center of the pad, then the energy goes to the connector, generaly in dark colours. the connector may burn.
With the Donut lens, the laser does reach the pad, but not the connectors.
Motorised solder feeding.

Steps on laser soldering
1- Laser come to heat the pad.
2- Solder Feeding which is spread around the pad, thanks to the energy provided by laser.
3- Solder is solidifying, the soldering process is over.

Laser allow to get a constant heat all around the pad. On the other hand, a conventional iron tip can heat only one side of the pad.

Japan Unix system can garanty a controlled solder feeding up to 0.2mm !
With this accuracy, every soldering issue in industry can find a solution
