Most commonly used to meet the high reliability requirements of the military and aerospace industry or in power electronics that generate a lot of heat, THT remains an effective PCB assembly method. However, although it provides stronger mechanical bonds, through-hole mounting requires a more laborious process making the boards more expensive to produce.
At Newbury Electronics, you can rely on our expertise to recommend the most suitable mounting technology for your applications, regardless of your niche.
As the name suggests, Through-hole assembly is a method in which components are inserted through holes drilled into printed circuit boards and are then soldered to pads on the opposite side. This process can involve both automatic and manual procedures which is especially useful for testing and prototyping.
Before surface mount technology came around, through-hole technology (THT) was the main printed circuit board assembly process used. However, SMT allows for high-speed production, permitting higher-density circuits and making through-hole mounting rarer and even discouraged sometimes.
It is far more efficient to machine assemble an electronic circuit if it is completely populated with surface mounted components. Leaded parts or through-hole components, on the other hand, are laborious to fit. They need lead trimming and bending, hand placement, further trimming and hand soldering. SMDs are simply machine picked and placed from a reel.
Yet, this technology is still used for some applications which is why we also offer through-hole assembly services. It involves component leads being placed into drilled holes on bare PCBs making it ideal for products that require stronger connections between layers.
