With the continuous advancement of global environmental protection regulations, RoHS, REACH, and other environmental standards have become the basic threshold for electronic product exports. Lead-free soldering has become the standard for most foreign trade orders. Lead-free solder has a higher melting point and worse wetting properties compared to lead-containing solder, posing higher requirements for the temperature control stability, preheating uniformity, and smoothness of the solder wave of wave soldering equipment. If the equipment has large temperature fluctuations, it is easy to cause problems such as poor solder wetting, cold soldering, and PCB delamination, resulting in export product quality inspection failure.

Dongguan Mingrui Technology Co., Ltd. has designed wave soldering complete machines according to lead-free process standards, with high temperature control accuracy and small temperature fluctuations, suitable for mainstream lead-free solder such as SAC305. The key components of the equipment are durable and reliable, meeting long-term uninterrupted production requirements; the complete equipment can provide corresponding technical materials to support customers' products to meet international environmental protection compliance requirements. Mingrui Wave Soldering can serve export manufacturing enterprises in home appliances, industrial control, energy storage, and communication, providing stable and reliable lead-free welding solutions for overseas customers.
