1, many foundries have vertical parts plug-in machines (such as vertical capacitors and DIP resistors). You can find some electronic products foundries online.

2. If you want to replace these parts with plug-ins, you must buy them from typing materials, that is, you can't buy them in bulk.

3. Now both resistors and small capacitors can be changed into patch parts, but the cost of changing large electrolytic capacitors from plug-ins to patches is much more expensive, and some power resistors are impossible.
