Types of PCB Assembly Service

GreensTone is focused on Turn-key PCB assembly for over 10 years. Our one stop
pcb service includes PCB manufacturing, PCB components procurement, SMT&Though-
hole, and pcb&pcba burn-in testing and programming.

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.

GreensTone provides through-hole pcb assembly pcba 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.

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.

GreensTone provide 1-10layers PCB manufacture, include FR4 and Hi-tg PCB
material with conventional Hallead-free HASL, Falsh Gold, ENIG (Immersion Gold)
OSP(Entek), Immersion Tin, Immersion Silver, Hard Gold and so on.

PCB Capability

PCB Surface



Heavy Copper PCB
Printed Circuit Board

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.
PCB Components Sourcing

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
Prototype 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.
Volume PCB Assembly

GreensTone engineers and manufacturing specialists bring a value-added
engineering approach to your project team.

Case Studies of PCB Assembly

How Long Does It Take To Assemble A PCB?
Depending on the production quantities, PCB production takes 3-14 business
days. For prototype run, it takes 3-5 business days. For volume run, it normall
takes 14 business days. PCB assembly normally take 5-14 business days for small
to medium volume production. The components lead time is uncertain, and for
normal parts, it can be around 2-4weeks, but for long lead time part like some
ICs from TI and Microchip, it would be longer. And it will depend on the lead
time which the suppliers provide.

What does PCB assembly do? A blank PCB soldered with electronic semiconductors
and components. GreensTone PCB assembly process is like this: You send us your
design file→ we arrange PCB manufacture and parts sourcing as per your files
request →parts receipt→Parts kit preparation →SMD manchine pragraming→paste
stencil fabrication→SMD manchine set-up→SMD verification of component's
footprints→assemble PCB top side→assemble PCB bottom side→ Through-hole wave
solder/hand solder assembly→ Touch up and testing→ Final QC&shipment
