25G optical communication BOX and PCBA laser welding case

How to solder 25G optical communication module BOX and PCBA? After a comprehensive evaluation, the process engineer of Zichen Laser decided to use the laser solder paste soldering process for proofing, first the solder paste is dotted on the pad of the Optical device BOX and PCBA, and then the solder paste is heated and fused with the laser, and a stable connection is formed after cooling, and the laser welding process directly uses 4 pads irradiated on the product with a large light spot, and the welding time is only about 3 seconds, and the final FPC and OSA welding effect is as follows:

Notice to Customers:

1. The object of laser soldering (pictures, samples or drawings), we need to evaluate it, if the evaluation is not in place, it will have a certain impact on the later equipment put into production.

2. The customer's cost budget and efficiency requirements for the laser automatic soldering machine, our sales engineers will develop a set of solutions suitable for customers according to the customer's efficiency requirements, and will make adjustments according to the customer's budget. However, efficiency and price cannot be both, you get what you pay for, and the return will not be high if the price is low.

3. Problems caused by synchronous belts - the laser automatic soldering machine will work according to the movement trajectory we set during the working process, so in the process of frequent reciprocating and long-term operation, the synchronous belt will wear out to a certain extent.
