MERAIF MFETS-350 Selective Wave Soldering
Selective wave soldering is a type of soldering equipment used in electronic assembly. It is mainly used to solder specific areas on a circuit board, rather than soldering the entire circuit board like traditional wave soldering. It precisely controls the height, speed and shape of the wave crest to apply the molten solder precisely to the area that needs to be soldered, such as a specific pin or component connection point. This helps avoid affecting other areas that have already been soldered or do not need to be soldered, reducing the risk of short circuits and improving soldering quality.
Feature:
1. The transport system adopts a new structural design and uses wear-resistant materials, which greatly improves the service life of the guide rail;
2. The spray exhaust system adopts a new concept, split design, and convenient and quick maintenance;
3. The forced natural air cooling system can meet the requirements of the lead-free process for cooling slope
4. The nozzle can be quickly disassembled and assembled to reduce maintenance time, from 3 hours to a few minutes;
5. The preheating system adopts an optimized micro-hot air circulation path, and the temperature in the temperature zone is more uniform and stable;
6. Built-in local selective spray device: the stepper motor moves in the X and Y directions through the synchronous belt, ball screw, linear guide, etc. to achieve local selective spraying of flux;
7. The streamlined design and internal modular design are suitable for lead-free soldering of SMT and plug-in components
8. The channel filter is double-grid format, which is convenient for maintenance, reduces filter tin blocking, and monthly maintenance is extended to March
