     Parts & Component Sourcing

    For PCBA prototype assembly , we accept components and parts in the following three approaches.

    1.Customer supply all the parts.

    2.Partial Turnkey,customer supply part components  .

    3.Full Turnkey, We purchase all the components from our Authority agent ,100% original guarantee.

    01

    Components for your PCBA project can be supplied in any one or more approaches above. We order genuine parts from your designated suppliers or our partner companies including DigiKey, Mouser, Arrow, Avnet, Future Electronics etc.

    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. Due to the complexity of how to determine the turn time of PCBA services, our policy is that turn-time begins immediately after all the parts are ready and all the PCB files (Gerber files/other PCB files, etc.,) , Centroid (Pick & Place PNP file, or XY Data or files in other formats), BOM, and all other necessary data or documents/images/photos are complete for our assembly work.
    2. 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.
    Turn-key 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.
    Partial Turn-key/Combo 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 5 pieces. 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.
    8. Component Package We accept parts in Reels, Cut Tape, Tube & Tray, Loose Parts and Bulk.
    9. Board Dimension
    • Min Board Size: 50mm x 100mm (Boards smaller than this size need to be panelized)
    • Max Board Size: 250mm x 500mm
    10. 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.)
    11. Board Type Currently we handles Rigid boards mostly. As we have the ability to handle flex and rigid-flex boards, please contact us if your boards are of flex or rigid-flex.
    12. Repair & Rework Repair and rework can be difficult, but we do. Our 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

    We perform multiple quality assurance procedures before shipping out any board. These include:

    Visual inspection,

    X-ray Inspection,

    AOI (Automated Optical Inspector),

    ICT (in-circuit test), and

    Functional test (test modules need to be supplied) .

     Quick turn lead times

    If all the parts are available, normally the PCBA prototype job can be finished within 3 to 5 days in our factory. This means that the order can be delivered within one weeks once assembly job start.

     Service Guarantee:

    We make sure to serve each customer professionally, truthfully and friendly to the best of our ability.  We will gladly re-work your project if your project isn’t 100% satisfactory.
