precautions
■
DO NOT mate/un-mate non-terminated plugs with non-mounted receptacles.
This may lead to damage or deformation of the contacts.
■DO NOT touch the exposed contacts of the receptacle with bare fingers. This may leave non-conductive film,
cause corrosion or electrostatic discharge, affecting performance of the connectors or sensitive electronic
components.
■DO NOT apply flux to the contact terminals when hand soldering the receptacle to the board. Wicking of the
flux into the electrical contact areas may lead to connection failures.
Soldering temperature: 340ç ±10°C, soldering time: within 5 sec.
0.15mm
Maximum of 0.03 mm at the connector center section, with both ends of the connector as reference points.
Refer to "Nylon Connector Use Handbook."
