Short buyer notes for pcb connector suppliers. Each note is a checklist. It is not a factory claim and it does not add search volume to a phrase.
Before you open an article, keep four numbers in your own file: pitch, contact count, quantity, and destination. A 0.100 inch row is 2.54 mm. A five-contact plug still needs a pinout. A waterproof housing still needs the ingress protection code printed on the quoted drawing. Gold thickness, when you care about it, is a microinch or micrometer figure, not the word gold alone.
The notes discuss solder versus crimp, tin versus a stated gold thickness, and new versus surplus headers. They do not rank factories. Connector mating cycle counts are treated as datasheet lines that need a method. TIA-568 is mentioned only when the wires leave the board into a premise cable plant.
