Trusted West Midlands Through Hole Assembly Services
What is Through Hole Assembly?
Through Hole Assembly (THA) is a traditional PCB assembly method where component leads are inserted into pre-drilled holes on a printed circuit board (PCB) and soldered for strong mechanical and electrical connections. This process ensures high durability and long-term reliability, making it ideal for industrial and high-performance applications.
At First Choice Assembly, we provide expert through hole assembly services in the West Midlands, using advanced soldering techniques, component insertion, and lead trimming to deliver high-quality, durable PCB assemblies.
