TechNova Circuits is based in Shenzhen. It started in 2010. The firm gives combined PCBA for medium runs (100-10,000 units). They focus on car and factory boards with 2-20 layers. Also SMT/THT assembly and simple sourcing. It has ISO9001 certification. The 15,000 sqm factory uses AOI for checks. Buyers like the 5-7 day wait times and quick email help. But fast choices are few. TechNova does well for fair prices on normal FR4 boards. Yet it misses the super quick samples of top ones.
ElectroFab Solutions began in 2012 in Dongguan. It offers one-stop services that stress daily gadgets like smart home items. They manage up to 30-layer rigid-flex PCBs. Also mixed assembly and world part buying. With IATF16949 car certification, the 20,000 sqm plant handles from samples to 50,000 units. Feedback points to good 7-10 day turns and useful chat help. They get praise for low costs. However, advanced HDI parts are not strong for them. So they fit best for simple IoT jobs.
QuantumBoard Tech started in 2009 in Hangzhou. It focuses on high-frequency and RF PCBs for telecom and medical needs. The one-stop set includes 4-40 layer boards with Rogers materials. Also fine-pitch SMT and full assembly for low-to-medium amounts. It is ISO13485 certified. The 25,000 sqm plant uses X-ray and ICT tests. Users praise the skill in impedance control and 10-day normal waits. They get good notes on tech talks. It is a solid choice for special needs. But prices are a bit high for samples.
Nexus Assembly Group began in 2011 in Guangzhou. It aims at new firms with cheap one-stop PCBA for under 5,000 units. They cover 2-16 layer FR4 boards. Also basic SMT/THT and kitted assembly. It has UL certification. The 10,000 sqm facility gives eye checks and 7-14 day turns. Low quotes and phone help get cheers from hobby fans. But they lack fine-pitch or quick services compared to Shenzhen big names.
