Operating mode of Aoyue infrared soldering stations

The heating of the elements results from the absorption der IR-radiation. Because the metal connections of the components only have a low absorption, which means they reflect the IR-radiation, the heat has to be conveyed to the soldering points mainly over the component itself, over the PC board which is also heated and via the surrounded air. For this reason one works with both radiators (Preheater from the underside and IR-light from the upper side ) to heat or preheat the whole surrounding area of the soldering point. The temperature of the single components can vary greatly. The absorption depends on the material and the wave-length and this in turn depends on the temperature of the radiator. The heating of large and thicker SMDs is slower than that of small and thin SMDs.

The infr-red soldering has the following advantaged and disadvantages.

Advantages:
• Simultaneous soldering process with high efficiency
• Efficient and particularly suitable for serial products
• Easy handlind of the IR-unit, user-friendly
• Temperature of the largest SMDs (high pin count ICs) is the lowest

Disadvantages:
• Temperature profile necessary.
• Temperature of the single components can vary significantly. Small SMDs, for example single semiconductors can be easily overheated.

The Aoyue 720 is an ingenious Rework System as handy as a tool. It can be used to process micro BGA components in mobile phones computers, telephones, video game consoles etc. Handling and operation are simple to come to grips with and the station runs safely and efficiently. This station enables high performant rework applications for most modern systems like: BGAs, BGAs SMDs, SMT Connectors without overheating these components. The heat is generated by means of infrared waves (IR) and not with conventional hot air. The moving and placing of the components can be achieved without protection shield or other tools becuase no air flow is used for soldering.

By non-contact measurement the soldering and desoldering temperature is determined (at the IR-light source and the quartz preheater), simple, fast and safe. After being sucessfully soldered out BGAs can be soldered again in place. No expensive nozzles are needed, the unit is complete and fully operational. Due to the adjustable PC-board surface preheater the user avoids misplacing the components or their distortion. Using this rework system is as simple as placing components on an empty pc board. the built-in screen shield protects the user against IR-radiation.
