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?

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.

What Others Are Asking

What is the proper zero orientation for a SMT LED?

According to IPC-7351, the cathode should be on the left for a molded diode. However, when I use component wizard of my suppliers to create a diode, it places the cathode (K) on the right. Does it depend on the manufacturer? How does the assembly house know which way is correct?

How do you handle a PCB that didn’t print correctly?

I did have one board come back with a manufacturer error – an extra bit of copper just a hair’s width across hidden underneath a component. It looked almost like someone’s eyelash had fallen onto the board just before photo etch. How should I deal with it?

How can I determine BGA land pad diameter for given ball diameter?

I’m working on a project which requires the use of a CSP package. The product’s datasheet provides ball pitch and ball diameter but nothing about the preferred land pad diameter.
How can the pad diameter be worked out from these figures assuming an NSMD land?
