What are molex connectors? What are they used for?

My PCBA supplier use molex connectors on the samples order. What are they? What does they feature?

October 11, 2023

Molex is actually a brand name, it’s a company that makes inexpensive nylon plastic-bodied connectors.

They are generally used for internal connections in electronic equipment. It plays a role in connecting components. It can be mounted on the ends of multiple wire bundles or on PCBs by soldering.

Its Pins and sockets are made of inexpensive stamped steel and brass. It can be crimped rapidly by semi-automated machinery to wire ends so as to insert into the mating connectors, soldered and PCB.

I forgot a resistor on my PCB prototype – how do I add one in?

I need to add a resistor into a data line on my project. The data line is a trace and carries low speed data. A through-hole resistor will be fine. The pins for both ends of the trace are exposed, but how do I add the resistor and remove the trace?

Who controls the process control block(PCB)?

Recently, I have learnt about kernel and find a question that who controls the process control block(PCB)?The kernel or the process itself? Does it differ in different platform (windows/Linux)? So far, I know PCB is controlled in hardware, but I can’t get to the right answer.

How do you usually organize SMT parts during PCB assembly?

Suppose one is hand-assembling a board with many SMT components. Unlike THT, SMT components are often not labeled. How might one keep small (<100) quantities of such parts properly organized during assembly? Are there particular tools? Storage devices? Methods?
