The proliferation of hand-held portable devices requires a large number of tiny connectors that are small in size, low in cost, high in performance and flexible. Let's take a quick look at commonly used miniature connector solutions from relative performance, features and benefits, size attributes, and per-total cost alignment. Kunshan connector

1. FPC connection to the board

FPC connectors are characterized by zero insertion force drive that repeats cycles with minimal wear. These miniature connectors feature a wide range of fine pitch options including push-pull and flick drive with the pre-assembled cover securing the connection between the FPC and the connector terminals.

FPC connectors provide board design flexibility for tight packaging. It saves money by offering a one-piece solution, eliminating the need for mating other connectors such as wire-to-board connectors or board-to-board connectors.

Some connectors are double contact designs, eliminating the need to procure two different styles of FPC connectors, which require top contact on one board due to cable construction and bottom contact on the other board. Some products have a unique FPC lock that helps provide positioning and cable retention while holding the cable in place for easy insertion. Such as the HRS connector FX16 is like this.

2. Miniature coaxial to board connectors

The FPC connector has been used to connect the main keyboard of a high-definition LCD device and a click-type mobile phone. However, these flexible solutions have problems with poor mechanical durability and lack of flexibility, electromagnetic interference (EMI) and the like. For example, a rotary phone LCD screen is required to rotate nearly 360 degrees in any direction, and the flexible circuit can not cope with such abuse. To absorb discrete EMI, ground traces or shields can be placed between signal traces. However, the additional traces will occupy more space, not conducive to the miniaturization of handheld devices. With a shielded FPC, the device has a hitting or rotating hinge, sacrificing flexibility and durability. HRS Hirose FX36 is one of the superior performance of miniature coaxial connector.

Micro coaxial connector with good shielding function, the pitch of 0.40mm or 0.30mm, the use of very thin coaxial 42AWG or 44AWG. Micro Coaxial Connectors As a line-to-board connector, the Micro Coaxial Connectors are widely used in the rotating hinge / neck area of mobile phones, digital video cameras, laptops, smartphones and IP network cameras.

3. Miniature board to board connectors

Four dimensions are important when designing a PCB with two small PCBs connected together:

(1) low height - stack height (H) is less than 1.00mm;

(2) low depth - narrow width connector is less than 3.00mm;

(3) small footprint - connector end-to-end size (with the circuit size and change);
