40G optical module FPC and PCBA laser welding case

40G optical module FPC and PCBA laser welding case

With the signal transmission rate being increased to 40G, the optical module design has increasingly stringent requirements for FPC and PCBA wiring, and the optical module FPC and PCBA laser soldering process is becoming more and more mature. The welding technology of optical devices of optical communication 40G module and FPC and PCBA has made rapid development in automatic welding. At present, the automatic welding technology of optical communication module on the market is mainly based on solder paste laser welding, with high welding accuracy, fast efficiency and high degree of automation.

Laser solder paste welding machine

How to weld 40G optical module FPC 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 FPC 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 PCBA 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.
