Improved reliability: PCBA allows for the precise placement of electronic components, which can enhance the reliability of the final product. Using automated assembly processes, PCBA can also help reduce the risk of human error and improve overall quality.
Increased efficiency: PCBA can help streamline the manufacturing process by allowing for the rapid prototyping and production of circuit boards. Automated assembly processes can also reduce the amount of time and labor required to produce a finished product.
Reduced cost: PCBA can help reduce the overall cost of manufacturing electronic products by minimizing the number of defects and rework required. Automated assembly processes can also reduce labor costs and increase production efficiency.
Enhanced performance: PCBA allows for using advanced components and materials, which can improve the final product's performance. High-density PCBA, can help increase electronic device processing speed and power.
Greater design flexibility: PCBA allows for using a wide range of components and materials, giving designers greater flexibility in their product designs. Mixed-technology PCBA,uses both through-hole and surface-mount components in the same circuit board.
Steps are involved in the PCBA process
Solder paste
In a traditional PCBA process, the application of solder paste to the PCB is usually the first step. It is very important to accurately place the correct amount of paste onto each of the pads that require soldering. Although solder paste does not typically need to be applied with THT, it is required for SMT.
Component placement
The second step in the traditional PCBA process involves placing the components on the board, which can be done either manually or with the assistance of machinery. If a THT approach is taken, incredibly precise hand placements are required. For SMT, though, robotic systems are utilized for component placement, which is just as precise but faster.
Reflow
Traditionally, reflow is the next step, which involves the solder being melted and resolidified. As the board and its components all move through an oven, the solder is heated and liquefied.
Connections are formed before it is moved into a cooler, where the solder cools and hardens again. In THT, reflow is not required, although the board must undergo a thorough inspection to ensure component placement accuracy.
Through-hole part insertion
Traditionally, through-hole insertion is manually done at the next stage once the board has undergone a visual inspection. Soldering may also be done manually at this stage, although a wave-soldering method may be used for certain processes as well, such as the THT approach. This involves the entire board moving through liquid solder and then through coolers to solidify this solder.
Final inspection and cleaning
In the traditional PCBA process, the last step involves a final inspection of the board, the solder points, and the components to ensure that no issues are present. Following this inspection, the board, solder points, and components should also be cleaned to remove any debris or excess solder. After this, assembled PCBs may be packaged for distribution or further manufacturing.
PCBA testing
Visual Inspection
This is the first step, where the board is checked for obvious issues like soldering defects, misplaced components, or visible damage.
01
Functional Testing
The PCBA is tested to make sure it performs its intended functions. This might involve checking the electrical signals, power levels, and other operational parameters to confirm that the assembly works as designed.
02
In-Circuit Testing (ICT)
This involves using specialized equipment to test each component on the board for proper function and connectivity. It helps to identify problems like short circuits, open circuits, and incorrect component values.
03
Automated Optical Inspection (AOI)
An automated system uses cameras to inspect the PCBA for defects that might not be easily visible to the naked eye. This includes checking for issues like solder joints and component placement.
04
Burn-In Testing
This test involves running the PCBA under stress conditions to ensure it can handle extended use without failure. It's often done to catch any latent defects that might not appear under normal operating conditions.
05
Step1. The first step in designing a custom PCB is to create a schematic view.
Step 2. Once everything is placed in its place, an electric rule check is run to ensure no evident faults.
Step 3. The components are moved to proper places that make good sense.
Step 4. For the board production, signals are assigned to each layer and varying signals on a single layer cannot touch.
Step 5. After the signals are laid, a design rule check needs to run to ensure the proper placement of holes, traces, etc. These rules can be customized as well.
Step 6. If the design is approved, the design files can be uploaded.
Step 7. Online quotation system and click "Browse Files" to upload Gerber.
