AiEInkSmart labels and base stations are built by three long-term partner factories in the Pearl River Delta, each with its own role. PanPanTech designs the Lite, Slim and Rock hardware, the firmware and the management software, and our manufacturing company places the production orders. Inspection is done jointly by our team and the factory. Below is what each site does and what it has.
Guangzhou: samples, small batches and new products
Our Guangzhou partner is the most flexible of the three and the closest to our office, so new products, custom housings, samples and small orders start here. The dispensing machines, pressure-holding fixtures and assembly tools we bought for our labels are installed on its assembly line, and our engineers work on that line when a new product goes into production.
- About 3,000 m² of production floor at a new site opened in 2026
- 4 automated SMT lines with a planned capacity of about 20 million placements a day
- 3D solder-paste inspection (SPI), AOI, X-ray and a first-article inspection system
- Depaneling, through-hole and hand-soldering lines, functional test and assembly lines
- MES, WMS and ERP; each board can be traced by serial number to its SPI data, placement offsets and reflow profile
- ISO 9001 certified since 2018; recognised as a national high-tech enterprise
Guangzhou: our own dispensing and pressure-holding fixtures, finished labels and AOI inspection.
Foshan: volume production
Our Foshan partner is the largest of the three. Once a product is proven in Guangzhou, large orders move here using the same production files and test criteria. We work directly with the plant manager, and the factory has the financial strength to take large orders on.
- 15,000 m² single building, in use since August 2025
- 8 SMT lines with about 10 million placements a day; SPI, reflow and AOI on every line
- SMT capacity for up to 100,000 label PCBAs a day
- X-ray, automatic first-article inspection, intelligent component storage and MES dashboards
- 3 assembly halls with 6 assembly lines, 4 packing lines, a cleanroom and high-temperature ageing rooms
- Reliability laboratory: climatic chambers, salt spray, UV ageing, rain, drop and transport-vibration testing
- ISO 9001, IATF 16949 (automotive quality) and BSCI certified
Foshan: SMT, assembly hall, reliability laboratory and label samples.
Shenzhen: Classic series and base stations
Our Shenzhen partner has built e-paper reading devices for many years and knows e-paper displays well. It builds the Classic series in 2.13", 2.66", 2.9" and 4.2" and the AES-AP01 base station used with the Classic, Lite, Slim and Rock labels.
- 3,200 m² plant
- 3 high-speed SMT lines with about 8 million placements a day and AOI on every line
- 2 post-soldering lines and 2 assembly and packing lines
- Automated RF test line and automated module testing
- 200 m² class-10,000 cleanroom for display work
- ISO 9001:2015 certified
Shenzhen: SMT line, assembly line and automated module testing.
