Import Differential Tape, Pcb Reflow Tape — Buy in Bulk from Supplier in Taiwan

Differential tape, also known as sandwich tape, is a double-sided adhesive film designed for PCB reflow processes. The model DSK565 features a polyester base film with a thickness of 0.164mm, one side coated with silicone adhesive and the other with acrylic adhesive. The silicone side bonds to low-energy surfaces like metal carriers, while the acrylic side provides strong adhesion to PCB substrates. Adhesion strength ranges from 0.05 to 0.10 kg/inch on the silicone side and 0.8 kg/inch on the acrylic side, enabling secure handling during high-temperature reflow cycles.

This tape is engineered for thermal stability, with polyimide variants available for repeated use under reflow conditions up to 260°C. The standard DSK series uses a layered construction: a high-temperature resistant film core with differing adhesive chemistries on each side. This allows selective bonding - strong hold on the carrier, controlled release from the PCB. Typical industry standards for such tapes include ASTM D903 for peel adhesion and IPC-TM-650 2.4.1 for thermal resistance testing. The material composition avoids halogens and meets RoHS requirements by default.

Buyers include PCB assembly houses, contract manufacturers, and electronics prototyping labs that require precise component positioning during reflow soldering. The tape is sold in rolls with custom widths and lengths, typically shipped in anti-static packaging. MOQ and lead time vary by customisation level; standard configurations are available for direct order. Buyers should confirm compatibility with their specific carrier materials and reflow profiles before bulk purchase.

Solar Plus Company operates from Taichung, Taiwan, with a physical address listed on trade platforms. The company is verified as a harbor-tier supplier, indicating active participation in export documentation and compliance systems. There is no public data on company size, years in operation, or client roster. The listing confirms technical capability in adhesive tape manufacturing but provides no evidence of ISO certification, lab testing facilities, or R&D team size.

The supplier responds to inquiries with no recorded response rate or average response time, suggesting limited or automated customer engagement. Their product focus is narrow: differential tapes for electronics assembly, specifically the DSK and SDA series. No claims are made regarding in-house production of film or adhesive, nor are any third-party certifications referenced. Buyers should treat this as a manufacturer of finished tapes using sourced materials, not a vertically integrated producer.
