◆Plug – micro-coaxial cable
Precautions and recommendations
Cautions for soldering
1. For the micro coaxial cable assembled to this connector, cable alignment process as shown in "Recommended cable" on
the page 1 is required before assembly.
1Width of ground bar shall be 1.05mm Max. including misalignment of overlapping, flush by cutting, side drop or soldering.
Using an inadequate cable will interfere the assembly to the connector. Forceful assembly and soldering could cause
mis-soldering and damage the product.
2Minimize the length of outer conductor beyond the ground the
bar.
3Length of cutting the extra cable should be 2.1mm Max.
Any longer cable may cause contact with the connector
ɹɹduring assembly and could damage the product.
Recommended minimum length is 2.0mm, but this can be
altered as long as good soldering ability is maintained.
4Pre-solder and coat the inner conductor at the cable end.

2. Recommended solder for the assembly is flux cored solder with
0.2mm dia. (Lead-free: Sn-3Ag-0.5Cu), 21mm length.
If additional flux is used, make sure to prevent wicking onto the
contact area.
Wicking onto the contact area will cause the contacts to fail.
3. Before soldering the cable and connector with a cable assembly
machine, check the points to avoid below.
1Misalinment of cable end to the terminals in pitch direction
2Excessive floating of cable end
4. Follow the recommended temperature profile shown below for
the soldering.

The optimum conditions for soldering can vary depending on cable type and length, and solder type. Be sure to check the
recommended temperate profile and adjust the conditions accordingly.
