Frequently Asked Questions
How many contact positions does the TSM-135-03-L-DH-A-K-TR provide, and on what pitch spacing?
The TSM-135-03-L-DH-A-K-TR provides 70 positions on a 0.100 inch (2.54 mm) pitch in a dual-row configuration. This high contact count at standard grid spacing makes it suitable for backplane connectors, dense signal buses, and high pin-count board interconnection on industrial and computing PCBs.
Does the tape-and-reel packaging on the TSM-135-03-L-DH-A-K-TR support automated SMT production lines?
Yes, the TR suffix indicates tape-and-reel packaging, which feeds directly into automated pick-and-place machines. This eliminates manual handling of individual 70-position connectors and supports high-volume SMT manufacturing with consistent placement accuracy and throughput.
When would a designer choose a 70-position dual-row terminal strip like the TSM-135-03-L-DH-A-K-TR over a higher-pitch board connector?
A 70-position, 0.100 inch pitch dual-row strip is chosen when the design requires a large number of signals in a compact footprint on a standard 2.54 mm grid without moving to fine-pitch connectors. It is preferred in cost-sensitive industrial or computing boards where existing firmware and PCB routing tools are already designed around standard 0.100 inch grid geometry.
What assembly considerations apply to soldering a 70-position SMT terminal strip like the TSM-135-03-L-DH-A-K-TR on a production PCB?
At 70 positions and 0.100 inch pitch, this surface mount terminal strip requires careful solder paste deposition across all 70 pads to avoid bridging or insufficient solder joints. Reflow oven profiling must account for the connector body thermal mass, and solder joint inspection with AOI or X-ray is recommended for production volumes of 1000 units or more.
