What are the advantages of a plated through-hole PCB?

Through-hole Technology: Advantages and Disadvantages

PRO CON
Easier for prototyping Higher board cost due to drilling
Strong physical connections Takes up more board real-estate
Heat tolerance PCB assembly process is more involved
Power handling capability Slower speeds

What is through-hole in PCB?

Through holes on a PCB refer to a hole that is drilled from the top and through to the bottom of a PCB, these can be plated (PTH) or non-plated (NPTH). Through holes became plated-through holes (PTH) in order for the components to make contact with the required conductive layers.

How are through hole PCBs made?

The thru-hole manufacturing process, as its name suggests, involves drilling holes into the PCB. The board house drills these holes where the components will go according to the client’s design. Once the holes have been drilled, the leads are placed through them.

Are there any through holes in a PCB?

The power and/or hot pins will be thru-hole while the other signal pins will be surface mount. As you can see, there are still plenty of reasons to use through hole parts on your PCB design.

Which is larger SMD or through hole PCB?

Through hole components are generally larger than SMD components, but that doesn’t mean that soldering through hole components are a walk in the park. Depending on the skills of the individual and how the PCB is designed, there may be some obstacles when through hole soldering is concerned.

What kind of milling board do I need for a through hole PCB?

Sacrificial waste board and facing end mill: When milling a PCB even the slightest variation in height across your copper clad board can ruin your isolation milling traces. To help reduce this from happening you need to mill a pocket the size of your copper clad board into a sacrificial waste board of 1×4, 1×6 or 1×8 plain pine board or equivalent.

What should feed rate be for through hole PCB?

I keep mine set to about 60-80mm/M for V bits you can use a high feed rate. If you are milling with a tiny flat end mill, then you need to consult a feed rate calculator but keep in mind tiny end mills do NOT like high feed rates and take far longer than a V bit.
