Is it good practice to use through hole soldering on PCB?
This is usually true when the PCB houses SMD parts on both layers. Either way, it is still good practice to optimize your PCB design for through hole soldering. For a start, ensure that the hole size and annular ring is adequate for the physical pin to be inserted and soldered.
What are the minimum electrical spacing requirements for through hole soldering?
Conductor/lead ends may be clinched, with the clinched length at least 1/2 the largest solder pad dimension, bent in the direction of the longest pad dimension. Clinched leads shall not violate minimum electrical spacing requirements. NASA-STD-8739.3 [8.5.2]
What happens if you put ground pin on through hole solder?
If the annular ring is too narrow, you’ll find that the solder has difficulties holding onto the pad. And excessive heating may tear off the pad from the PCB base. But that’s not the end of horror stories with through hole soldering. The ground pin is notorious for cracking or drying a solder joint.
Are there any pitfalls with through hole soldering?
One of the best ways you can overcome any challenge with through hole soldering and even through hole desoldering is learning the potential pitfalls involved with the two processes. While it’s true that machines are taking care soldering on most components, some through hole components are still being manually soldered.
How to keep the pins straight when soldering?
2 – Use a breadboard to keep the pins straight and stable when soldering 3 – Leave the soldering iron on the pad for a moment after you solder. This will bring all the components – the pad, the header pin, and the solder up to the same temperature so they will cool together to form a proper molecular bond.
Which is the best software for through hole soldering?
Creating footprints for through hole components require precision and strong PCB design software. OrCAD PCB Designer not only simplifies component creation but also offers a great range of standard footprint in its library.
