Manufacturing Process

Soldering Techniques

Express PCB assembly uses various soldering techniques to ensure the components are securely attached to the PCB. The most common technique is surface mount technology (SMT), which involves placing the components on the surface of the PCB and soldering them in place using a reflow oven. This technique is efficient and cost-effective, making it ideal for high-volume production.

Another technique used is through-hole technology (THT), which involves drilling holes in the PCB and inserting the components through the holes. The components are then soldered to the PCB from the other side. This technique is preferred for components that require a stronger mechanical bond, such as connectors and heavy-duty components.

Quality Assurance

Express PCB assembly places a high emphasis on quality assurance to ensure that the final product meets the customer’s specifications. The PCBs undergo various tests throughout the manufacturing process, including visual inspection, automated optical inspection (AOI), and functional testing.

Visual inspection involves checking the PCB for any defects or abnormalities, such as misaligned components or solder bridges. AOI uses a camera system to inspect the components and solder joints for any defects that may have been missed during visual inspection. Functional testing involves testing the PCB to ensure that it functions as intended.

Express PCB assembly also adheres to industry standards such as IPC-A-610, which provides guidelines for acceptable levels of workmanship for electronic assemblies. This ensures that the final product is of high quality and meets the customer’s expectations.

Turnaround Time and Prototyping
