BUsage Recommendations

2. Recommended manual soldering

3. Recommended screen thickness and

open area ratio (Pattern area ratio)

4.Board warpage

5.Cleaning conditions

6. Precautions

1. Recommended temperature profile

s Due to the extremely small size of the connectors, handling it with bare hands should

be avoided. Follow the recommendations given on the proceeding pages.

s Use of fluxes is NOT recommended.

s Different production lots may exhibit some discoloration of the insulator material. This

will not affect form, fit or function of the connectors.

s The connectors should not be used a sole PCB support. It is recommended to use

additional means of board support.

Refer to "Nylon Connector Use Handbook".

Maximum of 0.02 mm at the connector center, with both ends of the connector as reference points.

Manual soldering: 290±10ç for 3 seconds

Note 1: Up to 2 cycles of Reflow soldering are possible under the same conditions, provided that there is

a return to normal temperature between the first and second cycle.

Note 2: The temperature profile indicates the board surface temperature at the point of contacts with the

connector terminals.

Thickness: 0.12 mm

Opening are ratio: DS side 100%, DP side 84%
