Short processing time and inexpensive compared to other plating. Good wettability of solder during assembly.
The "Handa Leveler" is designed to apply a solder coat on the copper surface that forms the land area of printed circuit boards, with the aim of enhancing surface protection and wettability during assembly. The board is immersed in molten solder, and when it is pulled up, high-temperature air is blown from an air knife located above the solder tank to remove excess solder from the board holes, pad surfaces, and resist. This process ensures that only the copper surface is coated with solder. 【Features】 ■ Short processing time allows for high processing capacity ■ Relatively inexpensive ■ Good wettability of solder during assembly ■ High storage stability ■ Reworkable *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Solder Leveling Process】 1: Use chemicals such as acids to remove dirt and oxide films from the surface. 2: Apply flux to the front surface of the substrate for protection of the resist area and activation of the copper. 3: Process the substrate using a solder leveling machine, including solder immersion and other solder leveling treatments. 4: Clean the flux residues and solder debris from the surface of the substrate. 5: Inspect the appearance of the solder and check for hole clogging. (A hole checker will be used if necessary.) *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company operates as a specialized manufacturer of surface treatment for printed circuit boards. In particular, to respond to the recent demand for short delivery times, we offer same-day processing even for small quantities and a variety of products, and for urgent orders, we complete them while you wait. Of course, we also provide same-day shipping to remote areas. Recently, we have quickly introduced a lead-free solder dedicated leveling machine (made in Japan) to accommodate lead-free solder, which has been well received. If you are facing any issues with surface treatment for printed circuit boards, please feel free to consult us.
