PCB Assembly Capability

We have advanced PCBA equipment that enables our printed circuit board assembly capabilities, including but not limited to those listed below. We are constantly updating our equipment to keep us ahead of the curve. If your PCB assembly needs exceed these capabilities, please get in touch with us at  sale001@ntu-pcb.com, and we will respond within 24 hours if we can do it or not.

PCBA Capability

Lead Time

Our assembly time ranges from 24 Hours to a few weeks. Please choose the appropriate time option to fit your schedule and budget. Due to the complexity of determining the turn time of PCBA services, our policy is that turn time begins immediately after all the parts are ready. All the PCB files (Gerber files/other PCB files, etc.), Centroid (Pick & Place PNP file, 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


We prefer you supply all the parts for the PCBA services. In this case, please send us all the components with a BOM file and a detailed packing list indicating the item number, customer or manufacturer’s part number, and quantity in the kit.


Our wide and powerful parts sourcing network offers Turn-key PCBA service. We do not mark up the cost of the parts. 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 where 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 detail of the parts concerning price, quality, and availability.

3 Assembly Options

We offer both Surface Mount (SMT), Thru-Hole (THT), and hybrid. We also offer single or double-sided placement.

4 Types of Solder

We offer 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 to save money.


Component Size

Passive Component: we can accept components as small as 01005, 0201,0402.

BGA: We can handle a BGA of 0.3mm pitch for rigid PCBs and 0.4mm for flex boards with X-ray testing. (we can confirm the details according to the board design.)

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.

Board Dimension

Min Board Size: 10mm x 10mm (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 rectangles, you need to penalize the boards in an array and add break-away rails at the two longer paralleled edges of the panelized boards to ensure that the machine can assemble the boards.)

11 Board Type

Currently, we handle Rigid boards mostly. As we can handle flex and rigid-flex boards, don't hesitate to contact sale001@ntu-pcb.com if your boards are 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.

ISO Certification       

Testing Procedures       

NewTriunion PCB’s production facilities are ISO9001 certified to ensure we exceed your expectations.

• ISO9001 certified

• IPC610-D Test specification

• Pass rate ≥99.5%

• Quality complaint rate ≤ 0.1%

• Our list of PCB assembly capabilities allows our PCB customers to have the convenience of a “One-stop Solution” for their manufacturing and assembly needs.

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

• Visual inspection: general quality check.

• X-ray Inspection: checks for BGAs, QFN and bare circuit boards.

• AOI Testing: checks for solder paste, 0201 components, missing components and polarity.

• ICT (In-Circuit Test)

• Functional test (Following your test procedures)
