Notes(Note 1) The temperature is the surface temperature of the PCB in the vicinity of the connector lead part.
(Note 2) When‌
using nitrogen reflow process, please mount the product with an oxygen concentration of
1,000[ppm] or more.
Please contact a Hirose Electric representative if the concentration is below 1,000[ppm]
Soldering iron temperature: 340±10℃
Soldering time : within 3 seconds

Thickness : 0.08mm
Aperture ratio : 100% on the Receptacle side, 100% on the Header side
A maximum of 0.02mm at the center of the connector with reference to both ends of the connector.

Not recommended. If this product is cleaned, please evaluate the performance before using it.
Cleaning may cause a change in the mating/unmating properties as well as environmental resistance.

・Insertion or removal prior to board mounting may result in contact deformation.
・Avoid supporting the PCB only with the connectors. Support it by other means such as bolts, screws, posts, etc.
・Avoid excessive prying during mating/unmating as it may result in damage.
・Do not apply flux which will cause solder wicking during manual soldering.
・‌This product may have slight color differences due to production lot variability, but this does not have any effect on theperformance.
・Please refer to the next page for mating/unmating precautions.
・‌It is advised to secure the mated connectors to the board with housings and cushioning materials because the productcan disengage from FPC routing, dropping or other impact.
・‌Do not use the connector outside of the specifications (i.e., rated current, rated voltage,
PCB design and operating environment, etc.). Such usage could lead to material outgassing, ignition, or short-circuit, etc.
Refer to the specifications and guidelines for board pattern dimensions,board cautions, and connector treatment.
Please contact Hirose if connector usage in conditions other than those described in thespecifications and the guidelines is being considered.

Receptacle

1. Locate‌the guides and align the connectors to the appropriate mating position.
The connector has guide ribs on the receptacle for proper mating alignment.
Align the connectors with the guide ribs.
Metal cover guide(Outside)

Metal cover guide(Inside)2. When‌
the connector comes to the appropriate position, the connector will lower into place
as indicated by the change in mated height.
(Please align the connectors)

3. When‌
the connectors has lowered into place, the connector pair will be parallel to each other andcannot be moved back and forth or left and right.
Please complete mating from this state by applying force.
(Please align the connectors)(Please align the connectors)

4. Please‌make sure connectors are mated completely. If one side is floating or the connectors are mated at an angle,
please unmate and then redo the mating procedure following the steps described.

BK22 Series/0.4mm Pitch, 0.7mm Stacking Height, 15A Rated Current, Power/Signal Hybrid FPC-to-Board Connector【Connector Un- Mating Precautions】

Aug.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.

1. It‌ is recommended to remove the connector by pulling perpendicular to the connector mounted surface.
However, unmating FPC-to-board connectors can become more difficult with higher pin count connectors and thinner FPCs.

2. If‌ is difficult to remove the connector parallel to the mounting surface, remove it diagonally towards the pitch
direction. Do not remove the connector towards the width direction as it may put a large amount of stress on the contacts.

3. If‌ the FPC is not rigid enough, there is a possibility of solder peeling or connector damage.
Please check the repetitive operation of the FPC planned to be used in advance, such as during the early stage build.
Please do not remove the FPC by holding one corner and pulling at a diagonal as this will put a great amount of stress on the contacts.
