The choice of a PTH PCB assembly or an SMT PCB assembly  depends on many factors. 

1) Surface mount technology(SMT) allows for a higher level of automation, which means boards can be assembled at a faster rate. This allows you to handle large volumes of PCBS and is more cost effective than through hole technology.

2) If you have unique requirements, surface mount technology may be highly customizable and therefore the right choice. If you need a custom-designed PCBA, the SMT assembly process has the flexibility and power to deliver the desired results.

3) Using surface mount technology, components can be installed on both sides of the circuit board. This double-sided PCB assembly means that you can apply more complex circuits without having to expand the application.

4) If your application must withstand high stress levels (mechanical or environmental) during operation, then the best choice for PCB assembly is PTH PCB assembly

5) If your application must operate at high speed and at the highest level under these conditions, then PTH PCB assembly may be the right choice for you.

6) If your application must operate at high and low temperatures, PTH PCB assembly with higher strength, durability and reliability may be your best choice.

7) If your application must operate and maintain its performance under high pressure conditions, you should choose PTH PCB assembly. 

Of course, conformal coating is included in Ulectronics’s PTH PCB assembly services.

"Yes". We strive to provide customers with fast turnaround PCBA services in various ways to meet your needs for fast turnaround PCBA

Typical PCBA board processes include SMT assembly, PTH assembly, and manual assembly. But it takes a lot of small steps, tests, and checks.

There are many devices for manufacturing PCBA and manufacturing PCBS. The main equipment is listed here.

In the pcb assembly process, the following production equipment is required.

1) PCB cleaning machine

2) Solder paste automatic printing machine

3) Solder paste detection (SPI) machine

4) SMT machine

5) reflow soldering machine

6) Wave soldering machine

7) AOI test

The following production equipment is required in the PCB production process:

1) Film exposure machine

2) Drilling machine

3) Laminating machine

4) Grinding machine

5) Laminating machine

6) LDI exp

As mentioned above, PCB is short for printed circuit board. It is the carrier of electronic components. All components are connected via PCB to achieve electronic functions. PCB assembly is short for printed circuit board assembly. It refers to the process of welding components to the PCB. PCBS and components have their functions, but they only work as fully functional products after they are all soldered together.

Yes, Ulectronics will carry out a series of tests and inspections on all products. Here are the main methods of testing and checking in vision.

1) Electrical Test (E-test)

2)Automatic Optical Inspection (AOI)

3)ICT (In-circuit Test)

4)Functional Testing (FCT)

5)X-ray examination 6) Visual inspection

1) 1 week for only PCB assembly

2) 2-4 weeks for turnkey PCB assembly

3) 4-10 weeks for Turnkey box build assembly

Regarding the cost of through-hole PCB components, the following factors should be considered.

1) Cost of PCB

2) Processing cost of THT assembly

3) Parts procurement cost

4) PCBA test cost

5) Turnaround time

6) Quantity

7) Packing

We have been providing high quality PCB assembly services for 16 years. With our decades of engineering and production experience in the printed circuit board assembly industry, we have always been able to anticipate and avoid possible problems before starting manufacturing, and then fabricate and assemble PCBS correctly for the first time.

Our company attaches great importance to the quality of PCB assembly. A strict printed circuit board assembly quality control system has been established, from raw materials, manufacturing process, quality inspection to the operation of production equipment, PCB assembly is fully controlled.

Through 15 years of unremitting efforts, we have established a sound enterprise production management process, so that our production costs are greatly reduced. Low prices and high quality standards are our goals.

Fast delivery of PCBA with the highest quality standards is one of our company's greatest strengths, we offer one-to-one service and small batch production can be completed within a week.
