Types of PCB Assembly Service

01

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.

02

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.

03

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.

04

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.

05

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.

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
