JST JMC 30-Position Fine-Pitch Receptacle
The JST 30R-JMCS-G-B-TF(NSA) is a 30-position receptacle from the JMC series, designed as a board-to-board interconnect with center strip contacts.
At this pitch, the trace escape between pads is tight, typically requiring 0.20mm to 0.25mm trace widths with a fine-line PCB process. The 30 positions in two rows means the connector body spans roughly 7.5mm along its length, not counting the board guide features. Confirm the footprint matches your existing layout before committing to a surplus buy, since the 0.50mm pitch leaves no room for pad position errors.
Surface Mount Assembly Notes
The tape and reel packaging (TR) feeds directly into a pick-and-place machine. No through-hole posts — all mechanical retention comes from the solder joints and the board guide, so the PCB pad design and solder paste volume need to be right for the 0.50mm pitch.
