News & FAQ
- PCB – Printed circuit board. This is the bare board itself without any electronic components.
- PCA – Printed circuit assembly. This is the board populated with all electronics components.
- PCBA – Printed circuit board assembly. This is the completed board with all components.
The most common causes of failures in PCB assembly can usually be narrowed down to the following:
- Design Flaw (most common)
- Power failure on board
- Overheating due to component crowding
- Weak soldering points
- Prototyping & Rapid Turnaround
- All sizes of production runs
- Kitted and Full Turnkey (PCB & Parts)
- Through-hole & SMT assembly
- Part of Part (POP) capable
- Accurate processing down to 01005

Yes, U Choice offers a vigorous inspection and testing after every printed circuit board comes off the production line.
Conformal coating is a process of applying a thin layer of polymeric material to printed circuit boards (PCBs) and other electronic devices. The purpose of conformal coating is to protect the electronic components from environmental factors such as moisture, dust, salt, chemicals, temperature changes, and mechanical stress. Conformal coating also enhances the electrical insulation and performance of the circuitry.
Our Conformal Coating facility works as ‘selective’, it can apply a range of materials, and can be cured by ultraviolet (UV). It can jet any lines, dots, regardless of their size, shape, thickness, and can coate in three dimensions.
You are welcome to drop by for more details and to experience how the facility works. We are more than happy to make you estimates per your request.
We recently added a Programmable High & Low Temperature and Humidity Testing Chamber. It can create temperatures ranging from -40°C to 150°C (-40 to 302 Fahrenheit) and the relative humidity from 20% to 98%. Through this simulated extreme environmental condition, it can test the reliability, durability and performance of your finished PCB and the components used for the board.
