Company Profile (BQC)

Founded in Shenzhen in 2003, BQC launched its Penang, Malaysia factory in 2024 as a one-stop PCBA manufacturer for energy storage. We have 24 SMT lines in Shenzhen with annual PCS/BMS capacity over 50GWh. Our business covers energy storage PCBA, PV inverter, industrial, medical and automotive electronics. We enjoy priority chip supply from international brands and mature domestic alternative ICs to cut costs and shorten lead time. Our professional R&D team provides early DFM optimization, and we cooperate with top global energy storage integrators and battery enterprises. Shenzhen factory serves mass orders with full R&D verification; Malaysia plant handles medium & small batches for Southeast Asia, EU and US customers.

FAQ

Q1: Can you customize the control panel according to our exclusive technical requirements?

A1: Yes. We provide full JDSM joint design service, covering schematic design, PCB layout, component selection and DFM report output. We can customize power matching, communication protocols and protection logic as your specs.

Q2: What are sample MOQ, sample and mass production lead time?

A2: Small-batch prototype samples are acceptable. Sample lead time: 7–12 working days; mass production lead time: 15–30 working days. Mass inventory of mainstream MCU and power chips shortens delivery cycles.

Q3: How do you resolve chip shortage and long procurement cycle issues?

A3: We have stable authorized supply channels from original chip vendors, plus mature pin-to-pin domestic alternative chips, which reduce costs by 30% with a stable 6–8 weeks supply cycle.

Q4: What reliability tests will be implemented before delivery?

A4: All finished control panels pass full automatic FCT functional testing. Optional high-low temperature cycle, vibration and salt spray aging tests are available for marine and outdoor products. All test data is archived in MES for full traceability.

Q5: Can you assist customers in completing product certification?

A5: Our factory holds complete quality & environmental system certifications. We can supply full material certificates and test records to support customers' UL, CE, FCC, certification applications.

Q6: Is long-term technical after-sales support available?

A6: We provide full-lifecycle hardware technical consultation. Our internal software team can develop customized remote upgrade firmware as requested.
