GreensTone has successfully served customers with PCB manufacturing service in communication, industial devices, new engrgy, power supply, sensors, smart home applications control, smart industial control , medical devices and security control device and so on. 

GreensTone PCB Quality Control

1. PCB Files Checking Before manufacturing

For every orders we recieved, Gerber files should be checked by our PCB engineers before sending to production. Engineers would help to check the board edge clearance, drilling, pad spacing, impedance and routing. if the engineer finds a problem with the file or something can't be optimized, our engineers will contact the customer to confirm the files again. 

2. Raw Material Guarantee

The quality of the raw materials determines the quality of the finished products. GreensTone has been working with leading suppliers in the industry,and apply materials as to international standards and customer requirements, such as Rogers, Shengyi, KB (kingboard) sheet, Rohm&Haas, TAIYO for solder mask ink.

3. The Good Performace Production Equipment

To ensure the quality and reliability of PCB products, GreensTone continuously introduces advanced equipment to improve their pcb manufacturing capabilities, including:                                      

  • Automatic solder mask production line

  • LDI exposure machine                                         

  • Fully automatic PCB etching equipments line

  • Fully automatic PCB testing machine line

  • Fully automatic electroplating line

  • Automatic silkscreen printing production line

4. Quality Inspection Method

  • Comply with ISO9001:2015 requirements  

  • Production processes are in line with IPC standards

  • Basic visual inspections 

  • Rigorous electrical tests. 

  • Flying Probe Testing 

  • AOI (Automated Optical Inspection) 

  • Copper Thickness Tester

Yes, thanks for your update on the projects status,it’s good for me to make our order plan.

—— Pablo from Spain June 20th, 2019.

Your engineer check the files very carefully,thank you for it, it helps me a lot.

—— Mark from a leading LED strips supplier in Australia Match,8th 2018.

The goods arrived very well, the packing is good, thank you.

—— Antonio from Valladolid, Spain May 25th, 2017.

We've been worked with GreensTone for many years, there is no failure.

—— Wally Nunn from Australia---a leading Pool products manufacturer July13th, 2016.

I reached out to GreensTone Electronics to manufacture the circuit boards. After a few discussions, Rebecca could see the community focus of the project and went above and beyond to reduce costs, ensure delivery and filmed elements of the production for educational purposes. Manufacturing offshore isn't as easy as it appears on the surface so it was invaluable to have Rebecca believe in the cause and be an ally in the production working toward the same goal.

—— Mic. from Australia Feb. 10th, 2015, written on his Facebook.

Yes, thank you we received the 34x LC VMS TILE 1C REV A earlier this week. The assembly quality is very good.

—— Ruth from Australia April 9th, 2014.

Thank you for taking time to check it,you are very efficient.

—— Peter Astrom from Sweden Sep 8th, 2013.

Your engineer is very clever,thanks for the help to check the file's problem.

—— Tony from Australia July 21st, 2012.
