Asahi Chemical Research Lab (M) offers a wide range of soldering materials, including solder paste, liquid flux, flux paste, SMT bonding adhesives, flux and coating removers, solder resist ink and conductive paste solutions.

Technical Data Sheets (TDS) for commonly requested solder products are available. If a specific data sheet is not listed on our website, please contact our technical team for further assistance.

Asahi Chemical Research Lab (M)’s soldering materials are developed for a wide range of electronics and industrial applications, including household electronics, automotive systems, LED lighting, and other specialized sectors.

Yes. ALL Asahi Chemical Research Lab (M)’s products are compliant with RoHS and REACH regulations.

The primary differences between silver-containing solder pastes (e.g., SAC alloys such as SAC305) and silver-free solder pastes (typically SnCu- based) relate to alloy composition, melting temperature, cost, and performance characteristics.

Silver-containing pastes generally offer lower reflow temperatures and enhanced mechanical performance, but at a higher material cost. Silver-free pastes provide a more cost-effective solution, though they require higher reflow temperatures.

Voiding in BGA solder joints can be reduced by using Asahi Chemical Research Lab (M)’s low-void paste series and by following the recommended reflow profile to optimize flux activation and outgassing behavior.

Solder paste should be stored in a controlled environment between 0–10 °C (refrigerated). Under proper storage conditions, the shelf life is typically 6 months from the date of manufacture.

For detailed handling, storage, and usage guidelines, please refer to the product documentation.

Typical curing condition is 120-150 ℃ for 5 minutes using either a reflow oven or a dedicated curing oven.

Asahi Chemical’s Liquid Flux is used to remove oxides, enhance solder wetting and aperture fill, and improve solder joint quality in wave soldering, selective soldering, and rework applications.

Shelf life for liquid flux is 6 months for unopened products. Storage at room temperature (approximately 25 ℃) is recommended.

Containers should be kept tightly sealed after opening to minimize solvent loss and should be stored away from direct sunlight.

Yes. Certificates of Analysis (COA), Safety Data Sheet (SDS/ MSDS), and Technical Data Sheet (TDS) are provided with shipment upon purchase.

Yes. Trial samples are available for evaluation, subject to product availability and application requirements. Kindly contact our team for more information!
