How Effective Is LEDUV Curing Equipment for Photocuring in the Circuit Board Industry?
News 2025-12-13
With the rapid development of the electronic industry, electronic products are increasingly moving toward miniaturization and high integration. Through-hole components used in the past are no longer suitable for integrated circuits, especially large-scale and highly integrated ICs, which have to adopt surface mount devices (SMDs). This puts forward higher requirements for PCB (Printed Circuit Board) manufacturing processes and surface mount technology (SMT). Therefore, enterprises need curing equipment that meets higher standards for production operations. Let’s take a look at the application effects of LED UV curing equipment in circuit boards.
In PCB production, curing machines are required to fix components on the PCB surface or cure PCB inks and SMT adhesives. Traditional manufacturing processes use ultraviolet light emitted by high-pressure mercury lamps to cure the PCB surface. However, high-pressure mercury lamps generate a large amount of heat, leading to a rapid temperature rise on the surface of irradiated objects, and excessive temperatures are likely to adversely affect PCB boards. In addition, high-pressure mercury lamps have drawbacks such as high power consumption, heavy pollution, and short service life.
As a professional provider of UV curing and automation solutions, the conveyor tunnel-type LED UV curing equipment can solve the curing problems in PCB manufacturing processes as well as the defects associated with mercury lamp curing. Compared with high-pressure mercury lamp curing machines, LED UV curing machines feature higher luminous efficiency, extremely low power consumption, and a service life of over 20,000 hours. They adopt LED cold light sources for low-temperature curing, with no infrared thermal radiation or mercury content, achieving environmental protection and zero pollution. Meanwhile, the ultraviolet light output of LED UV curing machines is several times that of traditional mercury lamp irradiation. It enables faster curing without over-curing, shortens production time, and greatly improves production efficiency.
