Micro USB Connector (USB2.0)
Micro USB Connector 2.0 Mount Types - Vertical, Horizontal: Top mount, mid mount and bottom mount
Vertical Mount USB connector: Mounted at 180° on PCB.

Horizontal mount: Regardless of PCB connector orientation cable plugs are designed to have the same orientation (USB Symbol facing upwards):
- Bottom mount USB connector: Soldered to bottom side of the PCB.
- Mid Mount USB connector: Fits in to a hole cut in the PCB and is soldered to the bottom side of the PCB. As well as contacts it also has solderable feet which provide extra strength.
- Top Mount USB connector: Soldered to the top side of the PCB (also known as micro USB reverse type).

Reverse Mount Micro USB Connector USB2.0
The reverse B type (also known as top mount B type) allows customers to mount a horizontal Micro USB connector on the top of their PCB. The standard PCB mount type is bottom mount, where the horizontal micro USB connector sits underneath the PCB. Reverse types allow the physical body of the Micro USB connector to sit on top of the PCB but still accept µUSB cable plugs in standard orientation with the USB symbol facing upwards. B type connectors are polarised, and to allow the correct cable orientation customers must have cut outs in the PCB to allow space for the cable entry locking points on the bottom side of the connector.

Micro USB Connector - B and A/B Receptacle
- Ultra-small, almost 60% smaller than a Mini USB Receptacle - uses less space.
- Bottom, mid and reverse mount SMT types and vertical DIP type available for different design configurations.
- 5 pin right angle type, full compliant to USB2.0 (backward compatible to USB1.0 & 1.1).
- 30µ" gold plated contacts for low contact resistance (<30mOhm).
- Mid Mount requires a PCB cutout which allows height saving for space critical designs.
- PCB shell stakes and plastic peg options allow extra physical strength and solder process PCB retention.
- Improved durability for a guaranteed life of 10,000 mating / unmating cycles.
Vertical Micro USB Receptacle
Thru hole receptacles in straight orientation allow alternative design configurations. GCT's range of vertical Micro USB2.0 connectors offers an SMT type with cap which allows fully automatic pick and place and a thru hole versions with a choice of lead length for use with 1.00mm (.039”) or 1.6mm (.062”) thick printed circuit boards:
- USB3105 A/B type - Thru hole for 1.00mm (.039”) PCB thickness.
- USB3106 A/B Type - Thru hole for 1.60mm (.062”) PCB thickness.
- USB3130 B type - Thru hole for 1.00mm (.039”) PCB thickness.
- USB3131 B Type - Thru hole for 1.60mm (.062”) PCB thickness.
- USB3145 B Type - Thru hole for 1.6mm (.062”) PCB thickness, with stabiliser.
- USB3140 B type- SMT allows fully automatic pick and place by the use of an plastic cap. Two shell stake length options provide solutions for 1.00mm (.039”) & 1.6mm (.062”) PCB thickness.
All parts offer - 30µ” gold plating allowing 10,000 mating cycles, metal stakes for extra PCB strength and shell grounding.
USB3140 & 3145 offer the option of without mating entry face, for those designs where the customer wishes to design the lead in as part of a custom moulding.
Micro USB Connector - B & AB mating configurations
Micro B receptacle accepts Micro-B plug and NOT Micro-A plug. Micro-AB receptacle accepts both Micro-A and Micro-B plugs.
With the introduction of the USB Micro Plug, a new plug receptacle called Micro-AB was also introduced. It can accept either a Micro-A plug or a Micro-B plug.
An OTG product must have a single Micro-AB receptacle and no other USB receptacles.
The OTG cable has a micro-A plug on one side, and a micro-B plug on the other (it cannot have two plugs of the same type). OTG adds a fifth pin to the standard USB connector, called the ID-pin; the micro-A plug has the ID pin grounded, while the ID in the micro-B plug is floating. The device that has a micro-A plugged in becomes an OTG A-device, and the one that has micro-B plugged becomes a B-device. The type of the plug inserted is detected by the state of the pin ID.

On The Go (OTG)
- New standard for small form factor USB connectors and cables.
- The addition of host capability to products which have traditionally been peripherals only, to enable point to point connections.
- The ability to be either host or peripheral (dual role devices) and to dynamically switch between the two. Lower power requirements to facilitate USB on battery powered devices.
Micro USB2.0 Chosen standard EU smartphone interface
Though Apple currently uses its proprietary 30-pin dock connector for transferring data and charging its iPhone, iPad, and iPods, CEN-CENELEC and ETSI agreed that an adapter is suitable for compliance.
Apple, along with mobile phone competitors RIM, Nokia, LGE, Qualcomm, Samsung, Sony Ericsson, and others are hoping to streamline mobile phone connectivity, at least as it relates to charging devices.
