What is a through-hole PCB?
Through-hole technology, also spelled “thru-hole”, refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in PCBs and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated …
What is the advantages of using surface mount devices in design PCB?
Advantages of surface mount technology SMT enables smaller PCB design by allowing more components to be placed closer together on the board. This leads to designs that are more lightweight and compact. The process for production setup is faster when it comes to SMT when compared to through-hole technology.
When did they start using surface mount for PCB assembly?
This technique is older than SMT, and for many years, it was the standard technology used for PCB assembly. When surface-mount technology began gaining popularity in the 1980s, many people thought it would make thru-hole PCB assembly obsolete.
What’s the difference between surface mount and thru hole PCB?
Surface mounting technology, originally called planar mounting, began to become popular in the 1980s, and today, it’s used for the majority of electronic components. Surface mounted components, as their name suggests, are mounted to the surface of the PCB rather than inserted through holes in the board as with thru-hole assembly.
Which is the correct way to mount a PCB?
Modern PCBA designers choose between two primary methods for mounting the electronic components onto a PCB: Through hole and surface mount. Knowing more about each method is essential to ensuring you make the right choice for your intended application.
What makes a printed circuit board through hole?
The component types selected will influence the size and appearance of the finished printed circuit board assembly (PCBA). In the past, components with long leads would be inserted, usually by hand, into plated through holes on the PCB. The leads would then be soldered to form permanent interconnections with the holes.
