Through-Hole PCB Assembly Service
Through-hole PCB assembly is a method of attaching components to printed circuit boards. It involves inserting component leads through pre-drilled holes in the PCB, which creates strong connections between parts and the board. OurPCB offers expert through-hole PCB assembly services for reliable electronic products.











PCB Through Hole Assembly
Through-hole PCB assembly starts with drilling holes in the circuit board. Components are then inserted into these holes from the top side of the board, and the leads stick out on the bottom side. Finally, these protruding leads are soldered to copper pads, creating secure electrical connections.
This method works well for larger components and high-stress applications. It’s often used for power supplies, connectors, and specialized parts. Through-hole assembly provides strong mechanical bonds, which makes it ideal for products that may face physical stress or vibration.

Through-Hole PCB Assembly Services | FAQs
What is the difference between SMT and through-hole?
Through-hole technology (THT) requires drilling holes for through-hole components, however, SMT directly attaches parts. Through-hole vs. SMT components is a debate focused on mounting techniques in PCB manufacturing. Through-hole mounting offers stronger solder joints, whereas SMT allows compact PCB design for modern applications. Moreover, through-hole PCB assembly factories use a through-hole PCB assembly machine for large-scale production.
Which is better: SMD or through-hole connectors?
SMD connectors are smaller, making them ideal for high-speed PCB prototype applications. In contrast, through-hole PCB assembly cost is higher due to extra processing in a through-hole PCB assembly factory. PCBA services for volume PCB assembly often favor SMT for automation efficiency. However, through-hole mounting provides better mechanical stability for large parts like a capacitor.
What about stubs in through-hole PCB mountable connectors?
Stubs in through-hole PCB assembly equipment create signal integrity issues during the assembly process. Printed circuit board assembly services must consider stub effects in THT connectors to prevent interference. Additionally, high-speed designs using through-hole technology require careful layout in PCB manufacturing. Through-hole PCB assembly factories mitigate stub problems with precise drilling and shorter lead lengths.
