1. Understand the functional requirements of the connector
Suppliers need customers to fully articulate their needs or risk misinterpreting their needs; this is especially important when custom electrical connectors need to be manufactured.
2. Consider mechanical stress
Temperature, shock, and vibration all create stress between interfaces and circuits. Select connectors that avoid the effects of these forces. Use an interconnect system to minimize stress build-up between mounting structures and connection points.
Third, find out the current load capacity
As connector size decreases, so does the current-carrying capacity of the connector; typically, industrial electronic connectors can handle between 200mA and 500mA, which is about half the current rating of larger board-to-board connectors . To compensate for the lower current-carrying capacity, designers may need to increase the number of terminals.
4. Consider connectors early in the design
“Engineers tend to focus too much on the design of the overall system, putting industrial connectors in the design phase. Then they get caught up in their own design.” Designers must choose non-standard industrial connectors to complete the design, which not only increases cost and delayed delivery.
5. Understand the limitations of space
Although miniature BTB connectors are typically less than 1mm thick, they are also commonly used in tightly packed applications. To address potential packaging issues, designers need to consider circuit traces on the PCB, as well as additional wires to connectors.
6. Consider the stability of small/miniature connections
Failure to consider this issue in the first place can increase costs, and damaged industrial connectors need to be reconfigured, refurbished, and marked; even more expensive, field-replaceable connectors may need to be replaced, and such changes can add to the design time One to two weeks.
Seven, consider the ease of replacement
If the outside of the product is enclosed, then you'll need electrical connectors that can be replaced from the outside; otherwise you'll need to do some soldering work.
Micro-industrial connectors require foresight, requiring designers to anticipate a wide variety of factors such as packaging, durability, current-carrying capability, and replaceability.
