PCB Assembly Capabilities

Item Item Name PCBA Capability
1 Lead Time Our assembly time ranges from 24 Hours to a few weeks. Please choose appropriate time option to fit your schedule and budget.
2 a. Parts Source Consigned/kitted We prefer you supply all the parts for the PCBA services. In this case, please send us all the components with BOM file and detailed packing list indicating item number, customer or manufacturer’s part number and quantity in kit
With our wide and powerful network of parts sourcing, we offer Turn-key PCBA service. We do not mark up on the parts cost. Considering the big price gap between different suppliers, we only source from reliable suppliers who may have no price advantages. We will always ask for your approval before making any decisions.
This is our regular practice which you offer the main devices and components, while we source the rest for you. Just like the Turn-key service, we will ask for your approval on every details of the parts concerning price, quality and availability.
3 Assembly Options We offer Surface Mount (SMT), Thru-Hole (THT) and hybrid of both. We also offer single or double-sided placement.
4 Types of Solder We offer both leaded and lead-free (RoHS Compliant) assembly services for our customers. Please choose one to best fit your PCB and the parts on the PCB.
5 Stencils We use laser cut stainless steel stencils to ensure high reliability for fine pitch and BGA components. Nano coating is available upon request.
6 Minimum Order Our minimum is as low as 1 piece. We do not want you to pay for what you do not need indeed to save you money.
7 Component Size > Passive Component: we can accept components as small as 01005, 0201,0402. > BGA: We have the ability to handle BGA of 0.25mm pitch with X-ray testing. > Fine Pitch Parts: we can assemble 0.25mm fine pitch parts.
Component Package We accept parts in Reels, Cut Tape, Tube & Tray, Loose Parts and Bulk.> Min Board Size: 50mm x 100mm (Boards smaller than this size need to be panelized)
8 Board Dimension > Max Board Size: 250mm x 500mm
9 Board Shape We can assemble boards in Rectangular, Circular and any Odd Shapes. (For shapes other than rectangle, you need to panelize the boards in an array, and add break-away rails at the two longer paralleled edges of the panelized boards to ensure that the boards can be assembled by the machine.)
10 Repair & Rework BGA reballing service with which we can safely remove the misplaced BGA, reball it and put it back on the PCB correctly. It is cost-effective.

Testing Procedures

Various testing method will be applied to the assembled boards before the final shipment:


  1. Visual inspection: general quality check.
  2. X-ray Inspection: checks for BGAs, QFN and bare circuit boards.
  3. AOI Testing: checks for solder paste, Fine pitch components, missing components and polarity.
  4. ICT (In-Circuit Test).
  5. Functional test (Following your test procedures).
