Import Double-Sided Hasl-Lf Pcb — Buy in Bulk from Supplier in China

The double‑sided HASL‑LF PCB supplied by Shenzhen Ja Electronics Technology Co., Ltd. is built on FR‑4 substrate for robust thermal and electrical performance. It features a lead‑free hot‑air solder leveling (HASL‑LF) finish that meets RoHS requirements. The board accommodates a minimum wire spacing of 0.10 mm and a minimum drilling diameter of 0.20 mm, enabling fine‑pitch routing. A standard thickness of 0.16 mm provides compatibility with a broad selection of component assemblies.

FR‑4, a glass‑reinforced epoxy laminate, is the industry standard for multilayer PCBs due to its dimensional stability. The HASL‑LF surface finish offers good solderability while avoiding lead, which is essential for consumer electronics and medical devices. Typical copper weight for comparable boards is 1 oz/ft² (35 µm) per layer, though the listing does not specify the exact value. Standard operating temperature for FR‑4 boards ranges up to 130 °C, aligning with most assembly processes.

Manufacturers of smartphones, telecom equipment, automotive control units and diagnostic instruments often select this type of double‑sided PCB for compact and reliable circuit implementation. Shenzhen Ja Electronics indicates that MOQ and shipping conditions are negotiable, with options for L/C or T/T payment and various incoterms. Prospective importers should request confirmation of the copper weight, impedance control data and any applicable test certificates before finalising the purchase. Clarifying lead‑time expectations and packaging details will help align delivery with production schedules.

Shenzhen Ja Electronics Technology Co., Ltd. is located at Room 1003, Gu Shu Times Center, Bao’an District, Shenzhen 518100, Guangdong, China. It is classified as an imported‑tier supplier with a harbor trust tier, indicating verification of its basic business credentials. The platform records a response rate of 0 % and an average response time of 0 hours, so communication may require persistent follow‑up.

The firm lists double‑sided PCBs with a lead‑free HASL finish, targeting sectors such as consumer electronics, telecommunications, automotive and medical devices. No specific certifications, capacity limits or lead‑time figures are disclosed, so buyers should request IPC‑6012 compliance reports and production capacity information. The supplier mentions flexible trade terms including L/C and T/T, but exact conditions must be negotiated per order. Potential customers are advised to discuss packaging options and any required testing during the quotation stage.
