Import Flexible Circuits — Buy in Bulk from Supplier in India

Flexible circuits are thin, bendable printed circuit boards designed for applications where space and weight are constrained, such as medical devices, aerospace systems, and compact consumer electronics. These circuits use polyimide or polyester substrates with copper conductive traces, typically 18 to 35 microns thick, and can be single-sided, double-sided, or multilayer with plated through-holes. The supplier provides circuits with a minimum trace width of 75 microns and spacing of 75 microns, consistent with standard industry tolerances for high-density interconnects.

The base material is generally polyimide film with a thickness range of 12.5 to 50 microns, and adhesiveless laminates are used where thermal stability is critical. Copper foil is electro-deposited or rolled annealed, with standard grades being 1/2 oz, 1 oz, or 2 oz per square foot. Surface finishes include HASL, ENIG, or immersion silver, chosen based on solderability and shelf-life requirements. These circuits are rated for 200+ flex cycles at 10% strain, meeting IPC-6013 Class 2 standards for general commercial use.

These circuits are sourced by manufacturers of wearable health monitors, automotive sensor arrays, and drone flight control units, where rigid boards cannot conform to curved or moving parts. Buyers typically order in batches of 50 to 500 units, with lead times of 10 to 15 working days. Packaging is anti-static, vacuum-sealed with desiccant, and shipped in ESD-safe trays. Incoterms are usually FOB Gandhinagar Port, with payment terms negotiated per order.

S B Electronics operates from an industrial estate in Gandhinagar, Gujarat, with verified facility registration and active business documentation. The company specializes in custom flexible circuit fabrication for electronics manufacturers in India and export markets. There is no public data on company size, revenue, or years in operation. Response metrics show no recorded activity, indicating no automated or manual buyer inquiries have been processed through this listing.

The supplier does not claim certifications such as ISO 9001 or IPC certification, nor does it list any client names, production capacity, or equipment details. It provides no information on R&D capabilities or in-house testing. All claims are limited to the product description and address. Buyers should request proof of process controls and test reports directly before placing orders.
