Since 2005, We provided quick turn printed circuit boards and turnkey PCBA Solutions from prototype to production for over 5000 customers.

Union Electronic Technology Limited with over 15 years in PCB and PCB Assembly area in China who primary mission is to continually provide high-quality PCB &PCB Assembly service. We may not be the cheapest but certainly we are the most economical.

No. we will keep all customers’ data, so just provide an item description or project name in your purchase order.

We accept payments by PayPal, cash, bank transfer (T/T) or VISA. However, we will charge a 3% PayPal fee of the total amount.

No. Our prices exclusive GST /import tariff

We strictly follow IPC 6012 Class 2 and 3 for manufacturing.

We normally work with Gerber files (RS274X format). However, Altium Designer/DXP/Eagle is the most common format we also can accept. Other files please contact your sales to confirm.

Yes. However, please note that components exported to our offshore assembly facility will incur customs duty and may delay the project.

We can keep in our stock or return to you, whatever you prefer.

Our standard lead time for production assembly starts from 10-15 working days after availability of all components and PCB. Prototype assembly will be quicker and we can provide expedited services as well. The lead time main depend on components.

We have strict quality control throughout the phase of assembly. Visual Inspection, X-ray Inspection, AOI (Automated Optical Inspection), ICT (In-Circuit Testing)…

Yes.we have it ,if you need , please contact your service at UETPCB.

*100% Genuine Parts *100% NO Replacement Guarantee

Yes. However, we need to konw which parts should be mounted and which ones ignored.

PCB design files e.g. gerbers, NC drill data, technical specification etc. BOM (Bill of Material) – Please include manufacturer’s name and part numbers Assembly drawings or picture of already assembled boards, Pick & Place file (Centroid fiIe)

Reference designators ,part number, manufacturer’s name and part number ,Vendor name (e.g. Digikey, Mouser, element14 etc.), Vendor part number ,Part Quantity ,Any other information

Before making a PCBA quote, you must need to know some ordinary issues that might appear when prototyping. Because of the nature of PCBs, we can repairable these malfunctions easily. Now we provide some typical malfunctions to help prevent these kinds of errors.
 

1 .Damage in the traces

 
The trace of PCB is usually made of aluminum and silver. Using these kinds of materials might cause some damages to the traces. Powe surges, metallic dust contamination, and lightning strikes are the common causes of these damages. Generally speaking, people can repair these damages, and usually, any damage is easily visible.
 

2 .Physical harm to the PCB

 
This PCB failure is caused by environmental pressures or harms brought on by China PCB manufacturers during the PCB fabracation. Dropping the PCB or China PCB prototype is the commonest cause of this malfuction. This kind of malfunction can not repairable, once it occurred, the PCB itself must be substituted.
 

3 .Heat and humidity

 
Exposing PCBs to the environment of humidity and heat will cause thermal pressure. The thermal pressure might damage the electronic components and the soldering of joints. Improper copper weight or Plating issues usually cause higher stress.
 

4 .Faulty electronic component

 
The faulty components are another common reason that caused printed circuit board assembly difficulties and malfunctions. This kind of faulty includes overheating, aging, voltage surges, and corrosion. The actual damage caused by this reason can be read with a meter.
