XH5-N Half-Pitch SMT Connectors (Board to Board and Board to Cable Connectors)

Precautions for Correct Use

● Soldering Conditions

• ･Recommended Reflow Conditions
  Maximum temperature: 260°C
  Time: Within 20 to 40 s

​​​​​​​
These conditions, however, depend on the type of solder, the manufacturer, the amount of solder, the size of the circuit board, and the other mounting materials. You must check and select the actual conditions.

● Metal Mask Thickness for Cream Solder Printing

We recommend a metal mask thickness of 0.18 to 0.20 mm for cream solder printing.
These conditions, however, depend on the type of solder, the manufacturer, the amount of solder, the size of the circuit board, and the other mounting materials. You must check and select the actual conditions.

● Pin Deformation

The pins will deform if you subject them to an excessive load. Deformed pins will reduce solderability when the connectors are mounted. Do not drop the connectors or handle them roughly. Do not connect or disconnect connectors that are not mounted to a circuit board. Doing so may deform the pins.

● In case of welding on the automatic welding groove after reflow

To prevent the rise of flux, mask the circuit board positioning boss holes with tape before you perform automatic soldering. If you mount connectors on the edges of the circuit boards, make sure that the solder surface does not come into contact with the connectors and that flux does not adhere to contact surfaces.

● Board Mounting Precautions

Be careful of board warping. Warping that is too severe may cause faulty soldering.

● Application Precautions

• ･Confirm that there is no excessive misalignment or inclination in the mating contact portion between the plug and socket before mating the connectors. Make sure that the connectors are mated all the way to the back. If the connectors are not mated all the way to the back, contact reliability may be lost.
• ･Do not apply an extreme load during connectors insertion or removal. The connectors may be damaged, and contact failure may result. Twist the plug and socket as little as possible when mating the connectors. Not doing so may deform the terminals or housing or crack the housing.
• ･Do not insert a foreign object, such as tweezers, into the connectors mating contact portion. Doing so may cause the plating to peel off or deforming of the terminals.
• ･When removing the harness, do not apply load to the flat cable. Otherwise, damage to the flat cable or the crimped part will result in poor contact.

● Connector Crimping and Strain Relief Installation.

• ･The flat cable can be crimped only once. Do not remove the flat cable or the cover after crimping. Otherwise, damage or poor contact will occur.
• ･After crimping, check that the claw of the cover housing is completely engaged. If the claw is not completely engaged, make some necessary adjustment. Incomplete engagement of the claw will result in poor contact.
• ･The installation of the strain relief should be performed straightly. Inclined installation will result in damage.
• ･Once installed, the strain relief cannot be removed. Forcibly removing it will result in damage.
• ･Do not apply load by bundling the flat cable or bending it excessively. Otherwise, poor contact will occur.

● Storage

• (1) Do not store the connectors in locations subject to dust or high humidity.
• (2) Do not store the connectors in locations close to sources of gases such as ammonia or sulfide gases.
