How Does PCB Assembly Differ From PCB Fabrication?

PCB Assembly Differ From PCB Fabrication

When it comes to electronic product development, PCB assembly is a critical step in the process. The assembly process converts design files into functioning circuit boards with components soldered on accurately and reliably. It accelerates development cycles and facilitates testing, proof-of-concept, marketing and funding. Choosing a partner with high-quality prototyping, balanced costs and responsive turnarounds ensures maximum business value from the process.

Whether the project is complex or simple, the PCB assembly near me process must start with a clean board. This involves imaging and etching the layers of the circuit board before assembly. After the images and etching are completed, the technician uses an automated optical inspection (AOI) machine to verify that each layer matches up with its schematic diagram. If there is a mismatch, the technician will discard the defective board. This step is important because if the PCBs are not properly aligned, they will not function correctly.

The next step is the reflow process, which heats the PCB to melt the solder paste and bond components to the board. Depending on the design, the manufacturer can use either manual or automatic placement tools to place surface mount (SMT) and through-hole components. The robot is programmed with the bill of materials and the pick and place file, which contains the location of each component on the PCB. Then, the robot applies the SMTs to the PCB. This is a time-efficient process that saves significant manufacturing costs for customers.

For through-hole components, the reflow process is performed with a selective soldering machine or by hand, depending on the quantity and the design of the circuit board. The board is then washed and inspected again for any defects. The last stage of the PCB assembly process is functional test, which tests the components to make sure they perform as intended. The PCBs are tested in a simulation of the real-life environment, which helps ensure that the devices will work correctly.

A reliable pcb assembly near me company will provide a detailed quote before beginning production. The cost varies based on the number of units you need, your technical specifications and PCB quality standards. You should choose a supplier that is capable of producing your unique PCBs in a timely manner and with exceptional quality.

The best way to evaluate a PCB assembler is to ask them for a quote and look at their website to see how many different types of PCBs they have made in the past. You should also talk to them about the number of units you need, your design and any other special requirements for your PCBs.

A good EMS provider will have a proven track record, excellent customer service and the latest technology to offer you a high-quality PCB assembly at competitive prices. A reputable EMS provider will be able to handle HMLV and HVLM orders and provide an exceptional turn-around time for your pcbs. Green Circuits is a trusted and experienced EMS provider that offers a full range of pcb services, including prototype and high-volume production. They can handle any type of pcb assembly project, from simple to complex and provides a one year limited warranty.
