Detailed Description:
The board has four relays driven by ULN2803 IC. The board works on
12V but the input signal can come directly from microcontroller output
working at 3V or 5V to control relays. Each relay can switch variety of AC
or DC high voltage, high current loads working at 110V or 220V AC mains
like lights, fans, and motors and such. The status of relay is indicated by
individual LEDs.

If you want to ensure the good quality for delivery of every board, the PCB programming, and PCB functional test is the best way to test.
PCBA Online Programming:
Before finishing welding, we usually program the microcontroller in the PCBA board to enable the microcontroller to achieve specific functions. It will improve efficiency and reduce production costs.
PCBA Test
Including ICT test, FCT test, Burn-In Test, fatigue test
ICT Test (In-Circuit Test)： Through the test probe contacting the test point of the PCBA, the main PCBA test circuit continuity, voltage and current value, fluctuation curve, amplitude, noise, etc.
PCB Functional Test Requirements
Before discussing design, test systems, software, and test methods, it is important to understand the "object" - the PCB product to be tested, not only the PCB or final assembly itself, but also how much will be produced, the expected failures, etc., including
Product type
Structure (single PCB / pre-made PCB / final product)
Test specification plan:
test point expected production (per line / per day / per shift, etc.)
Expected failure type
Obviously, the above ignores the "budget", but only after understanding the above items to determine how much a product test to spend, to figure out what is needed to PCB functional test-the UUT before you start discussing funding issues, and only at this time to know how to make compromises to get the job done.
PCB Functional Test Requirements
PCB Functional Test & Programming Quality Control
FCT Test (Functional Test):
Firstly we need to program the prepared single-chip microcomputer (MCU) into the program IC through the burner, this step is conducting a simulation test for all PCBA tests. Then it has any questions from hardware and software, we will also be equipped with the necessary patch processing production tooling and test racks.
Burn-In Test：
After the online PCB programming and FCT for the PCB board, we can simulate user input and output for a long time and periodically test its durability and welding reliability.
Fatigue test：
It is mainly to sample the PCBA board, and perform the high-frequency and long-term operation of the function, observe whether there is a failure, and judge the probability of failure in the PCB board testing, so as to feedback the working performance of the PCBA board in the electronic product.
In order to make sure nothing goes wrong, we will carry out strict inspection procedures to ensure the delivery of high-quality products.
Significance of PCB Functional Test
PCB functional test is becoming increasingly important, however, the same as PCB programming online test, the technology development, and PCB design can make the testing scope limited. Although great progress has been made in the PCB testing software environment to help overcome some of the difficulties, if you want to follow your test strategy to successfully implement PCB functional testing, there are many problems to avoid and to do more thorough preparation. PCB functional testing is increasingly being used in post-production line processes and even for mid-process testing, but the systems and implementation methods are almost completely different from those of the past. Today's PCB functional testing systems are in most cases faster and more compact, and PCB functional testing is indispensable for verifying overall product functionality, maintaining calibration information, providing data to ISO 9000 programs, and assuring the quality of high-risk products. Such as the quality of medical equipment are indispensable.
Flexible PCB assembly offers several advantages over traditional rigid PCBs, such as improved reliability, reduced weight and size, enhanced design flexibility, and simplified interconnection. These benefits make it a preferred choice for compact and portable devices that require a high degree of flexibility and durability.

The PCB assembly service is an important part of electronics manufacturing. Its role is to mount electrical parts on printed circuit boards with the help of surface mount technology and then it is plated with the help of hole technology. PCBA assembly China is also referred to as printed wiring assembly, electronics assembly, and circuit card assembly. By Looking at the different quantities of circuit boards to assemble, there are a few other types of assembly like batch PCB assembly, prototype assembly, small batch PCB assembly, and high volume PCB assembly.

The benefits of GreensTone’s turn-key PCB assembly service can be utilized for clients who require a convenient, quick turnaround for the prototyping of printed circuit board designs. GreensTone, a prototype pcb assembly supplier, is a global specialist in cost-effective prototype PCB assembly services. We have an in-house staff of seasoned experts who can take a client’s PCB designs from the parts sourcing, prototyping and assembly stages through a prototyped final product that can be shipped in typically four weeks if all the supporting documents are correct and there are no supply chain obstacles.
Prototype PCB Assembly Capabilities Overview
GreensTone china pcb prototype service is built upon the same processes of our hallmark turn-key PCB assembly service.
We use the same in-house expertise and resources to prototype a PCB in limited amounts up to 25 printed circuit boards.
Our prototyping team consists of solder techs, SMT-process engineers and parts sourcing associates.
Our supply team can source your parts from quality distributors, including obsolete or hard-to-find components.
The time saving benefits of our supply team alone give our clients both convenience and enhanced productivity realizations.
At the client's request, our supply team will optimize the type of packaging (e.g., bulk, tubing, or tape, etc.) to decrease your costs for orders with a limited bill of materials.
When required, we can prototype a client’s PCBs using a parts kit.
In addition, we are able to cross-reference parts or components when your specific types are not available. All component substitutions are approved by the client prior to their ordering or use in an assembly process. The client always maintains control of the final product.
Prototype PCB Assembly Processes
Our PCB prototype assembly processes enable clients to obtain even complex designs with GreensTone’s highly reliable Design for Manufacturing (DFM) and Design for Testing (DFT) services that guarantee a prototype built per your specifications in a quality-controlled manner.
We have developed assembly facilities specifically set up for proto assembly orders. These special facilities are flexible and permit the use of manual and/or automated component loading stations. Our facilities are capable of processing fine-pitch parts as well as ball grid arrays for high-density, FR-4 circuit boards.
After a client’s engineering documents are reviewed by GreensTone’s staff, and all parts sourcing issues resolved, prototype PCB fabrication commences after all components are procured.
On-time delivery is a value we share with all of our customers. We make a concerted effort to communicate any engineering, parts or process issues with our customers. However, the assembly process usually takes about two weeks.
