Import Double Side Pcb/Pcba With Lead Free Hasl — Buy in Bulk from Supplier in China

Xing Da Circuits Technology Co., Ltd. offers double‑side PCB/PCBA fabricated with a lead‑free hot air solder leveling (HASL) finish. The boards are built on FR‑4 laminate and can be produced up to a maximum size of 600 mm × 600 mm. Available board thicknesses range from 0.2 mm to 3.2 mm, and copper weights can be selected from 0.5 oz up to 11 oz per square foot. Surface‑treatment options include lead‑free HASL, OSP, immersion gold and gold‑plated coating.

FR‑4 is the industry standard substrate for commercial electronics, providing a dielectric constant around 4.5 and a glass transition temperature near 130 °C, which matches the typical performance envelope of most consumer devices. Board thicknesses below 0.8 mm are commonly used for compact handheld equipment, while thicker 1.6 mm or 3.2 mm panels suit power modules and rugged applications. Copper thicknesses of 1 oz and 2 oz are standard for signal and power layers, and higher weights such as 5 oz or 7 oz are employed when current carrying capacity is critical. All panels are manufactured to IPC‑A‑600F visual standards and undergo MIL‑STD‑105D Level II sampling for dimensional control.

The boards serve a broad selection of sectors including home appliances, digital cameras, LCD televisions, medical equipment, telecommunications, LED lighting and mobile devices. Small‑quantity runs and engineering prototypes are accepted, with a quoted prototype lead time of five to seven days and nine to thirteen days for larger batches. Xing Da provides OEM support and a 24‑hour rapid‑prototype service, and ships the finished PCBs in vacuum‑packed plastic bags placed inside standard cartons. Buyers should confirm preferred incoterms, payment terms and any additional testing requirements directly with the supplier.
