Turn-key PCB Assembly
GreensTone is focused on Turn-key PCB assembly for over 10 years. Our one-stop service includes PCB manufacturing, PCB components procurement, SMT&Though-hole, and PCBA burn-in testing and programming.
SMT PCB Assembly
GreensTone SMT production runs with automated SMT production processes, including single- or double-sided component insertions. All-in-one SMT assembly includes PCB manufacturing, Components placement, SMT stencil, SMT assembly prototype run and SMT assembly in batches run.
China Through-hole PCB Assembly
GreensTone provides through-hole PCB assembly services to meet conventional lead assembly requirements of a variety of industries. We provide single, double-sided, as well as high-density multilayer Plated Through Hole (PTH) circuit board assembly services to meet low to mid volume production.
BGA PCB Assembly
GreensTone mostly uses X-ray inspection for analyzing the features of BGA PCBs. This technique is known as XRD in the industry and relies on X-rays for unveiling the hidden features of this PCB.
PCB Capability
GreensTone provides 1-8 layers PCB manufacture, including FR4 PCB, Hi-tg PCB, thick copper PCB, single layer or multi-layer PCB with conventional HASL, Lead-free HASL,Falsh Gold, ENIG (Immersion Gold) OSP(Entek), Immersion Tin, Immersion Silver, Hard Gold and so on.
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.
FR4 PCB
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.
High-TG PCB
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.
PCB Components Sourcing
GreensTone Electronics employs a dedicated, parts sourcing and procurement team to manage the logistics and procurement of PCB assembly components using a quality-controlled and time-tested sourcing system that guarantees faultless electronic parts sourcing.
Prototype PCB Assembly
GreensTone prototype PCB assembly service is built upon the same processes of our hallmark turn-key PCB assembly service. We use the same in-house expertise and resources to prototype a PCB in limited amounts up to 25 printed circuit boards.
Volume PCB Assembly
GreensTone Electronics is an electronic contract manufacturer (ECM) that specializes in volume, turnkey PCB assembly services. The volume turnkey service utilizes a Design-for-Manufacturing (DFM) and a Design-for-Testing (DFT) service.
