TIA568 Wiring Standards
How to decide which wiring pattern to use:
1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.
If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

The Weller Advantage:
- Features digital temperature control with easy to read LED display for fast and accurate temperature set of the hot air
- Programmable using the optional WCB1 control module. Allows for temperature lockout for process control, temperature setback and °F to °C conversion
Applications:
- Rework and repair of SMT boards. Sensitive applications requiring non-contact hot air. Some ground planes and multi-layer boards.
Additional Product Features and Benefits:
- Air flow is adjustable using knob on the side of the power unit
- Compact design is ideal for soldering, desoldering, and rework of SMT components
- Uses fast acting shop air or compressed nitrogen
- Air flow is actuated by a finger switch on the hot air pencil
- Full range of hot air nozzles is available on page 21
- ESD safe to protect sensitive components
