Low-temperature solder paste OM550 is a lead-free, no-clean, halogen-free low-temperature solder paste designed for the through-hole soldering assembly of temperature-sensitive components. Electronics assemblers can use it to reduce or eliminate wave soldering or selective soldering processes when using hybrid technology. Low-temperature solder paste OM550 solder paste provides low reflow temperature while providing an extremely high yield of printing and reflow processes in through-hole packaging applications. In addition, it can print as small as 0.30 mm (0.12 in.) circular pads at speeds up to 100 mm/s (4 in./s). The online test of OM550 solder paste has a high pass rate and meets the requirements of IPC, Bellcore and JIS electrical reliability standards. It has excellent anti-cavity performance, full and bright solder joints, high electrical reliability, and high-cost performance!

Advantages of OM550 lead-free solder paste:

1. Eliminates damage to temperature-sensitive components and connectors by eliminating the need for peaking or selective steps;

2. The cycle time of the reflow process is significantly reduced;

3. Reduced energy consumption;

4. A no-clean solder paste, the residue after soldering is colorless, transparent, and easy to penetrate;

5. With good needle side performance, it is suitable for automatic test equipment testing;

6. The residue is soft and non-sticky, which reduces the false detection rate in needle testing;

7. The temperature adaptation range is more expansive and has good process compatibility. As a result, boards with complex designs are easier to get good welding results.

Scope of application:

ALPHA leads the technical trend of solder paste product development to meet the requirements of today's increasingly complex SMT process. ALPHA solder pastes can be used to assemble printed circuit boards for various product applications, including soldering handheld electronic devices, computers, consumer electronics, network servers, automotive systems, medical and military equipment, and many others.
