PCB Surface

Common PCB surface treatment technologies which GreensTone may use when manufacturing PCBs are HASL (hot air solder leveling), organic coating (OSP), electroless nickel/gold, immersion silver, immersion gold, and etc.
PCB Surface


FR4 is the most important material in the PCB assembly. Electric engineers and technicians normally design PCB boards with the FR4 PCB. There is a big demand for FR4. FR4 printed circuit board is normal and easy to design. The FR4 PCBs are popular as they are cost effective and can be widely used.


Normally FR4 Tg is 130-140°, moderate Tg is over 150-160 °, High-Tg is greater than 170°.The higher of Tg, the better performance of PCB moisture resistance, heat resistance, chemical resistance, stability and other characteristics.

Heavy Copper PCB

Thick copper PCBs are characterized by being covered with copper thicknesses from 3oz to 400 µm. These PCBs are used for high current outputs and high thermal management. The heavy copper allows PCB for high currents load and encourages heat radiation.

What is PCB?

What is PCB?

PCB is the abbreviation of the printed circuit board. PCB composed by insulated baseboard, pads for electronic components and copper foil connecting wires. PCB can replace complex wiring to achieve circuit connection between components in the circuit.

PCB is the motherboard of electronic components. Before the advent of PCB, the interconnection between electronic components was done directly by wires.  Today, PCB has been widely used in the electronics industry, due to the  PCB tecnology, manual wiring errors can be avoided, and electronic components can be automatically DIP or SMT pcb assembly, automatic soldering, and automatic detection, ensuring the quality of electronic device and improving labor productivity, reduce costs as well.


What Is the Difference Between PCB And PCBA?

What Is the Difference Between PCB And PCBA?

PCB is a blank circuit board without any electronic components soldered on. It just composed by baseboard with pads and copper foil connection wires. 

PCBA is a complete assembled board with electronic components. We apply surface mount technology and through-hole soldering technology solder the components onto the board. The components are soldered to the board can be SMD, through hole, UBGA, QFN, POP, leadless chips, connectors and terminals.

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.
