Pre-Heater
Pre-Heaters provide fast, efficient underside heating and reduce the possibility of thermal damage to sensitive components. They make soldering and desoldering easier by reducing the heat requirement of the soldering tool. This reduces the risk of thermal damage. They are used in a variety of applications such as circuit board repair and rework of digital cameras, cell phones, and other electronic devices. Pre-heaters are available in a variety of sizes and styles to meet a range of needs.
Pre-Heater Applications
-
Preheat the circuit board under repair
-
Reduce the possibility of thermal damage
-
Reduce the heat requirement from the soldering tool
-
Make soldering and desoldering easier
-
Soldering Pb-free assemblies
-
Rework of digital cameras, cell phones, PDAs, and MP3 players
-
Reduce thermal shock to the board and components

Bench top Board Heater
This video demonstrates the Hakko FR-1012 Pre-heater. It is a bench-top board heater designed to elevate the temperature of printed circuit board assemblies so that the components on them can be soldered and de-soldered more easily, and with improved results. This is particularly useful on medium to high-mass board assemblies, which can "heat-sink" a significant amount of energy being supplied by a soldering iron tip or handheld hot-air tool. This tool is particularly useful when soldering Pb-free assemblies.

Background on Soldering Equipment
Soldering is the process of bonding two or more metal items by filling the joint with a material called solder. It differs from welding because the pieces being joined are not melted. Instead, the filler metal is melted and flowed into the joint.
The basic solder equipment needed is a solder iron and a soldering station. However, there are many options and accessories available to meet a variety of soldering needs. When purchasing soldering equipment, it is important to remember two things:
-
Temperature and variable control are key. These features will help improve soldering, so be sure to consider the temperature ranges and variable control when choosing a soldering station
-
Keep extra nozzles and tips on hand. These are inexpensive and consumable. It is easier and more cost effective to purchase extras in advance rather than place another order and pay for shipping in the future
Soldering equipment is used by professionals as well as hobbyists. One of the benefits of soldering is that the process is reasonably permanent but reversible. Desoldering tools are available to remove unwanted solder.
