As GreensTone CEO said, GreensTone has over 10 years of experience in the China turn key pcb assembly industry. Our core values are centered around customer service, engineering, manufacturing, and product solutions. In the beginning, we gained a stellar reputation through China turnkey pcb assembly services and our customers pushed us to help them find solutions for PCB Fabrication, Components, Interconnect, Cables, Packaging Systems, and Mechanical parts in plastic or metal. Our expansion into these areas has allowed us to provide our customers with a wide range of engineering and manufacturing capabilities. Our core business is PCB assembly!

China Turnkey PCB Assembly Quality Control Process
Assembly manual instruction

The PCBA engineer of prototype pcb assembly supplier GreensTone make the assembly manual instruction to norm the manufacturing process in advance, guide the production, and improve the quality from the process technology

IQC Incoming Quality Control

Check all the components values, pads size, brands, manufacturing date and code

SPI Solder Paste Inspection

Solder paste inspection can check the solder paste is sufficient and uniform to prevent assembly quality problems in advance caused by poor solder paste soldering

Online AOI Inspection

The AOI can check the short circuit, offset, wrong solder, reverse solder, false solder, empty solder, incomplete solder, etc. It also can check excessive solder, less solder, continuous solder and solder joints.

First sample confirm

Check the first China turnkey pcb electronics sample with Gerber, BOM and coordinate files, test it's function with the testing program. Only sample confirmed by PCBA engineer, it can go for mass production.

Off-line AOI inspection

Check the soldered surface mount assembly for errors, omissions, and false connections.

X-Ray welding inspection

Inspect the solder joints of invisible components like BGA.

QC manual inspection

The assembled board is visually inspected to ensure 100 % ok.
