Martin has expanded its EXPERT 04.6 rework station series with a new configuration to rework LEDs and power components on heavy (metal or ceramic) boards.
The new EXPERT 04.6IXM was introduced at SMT Nuremburg 2012 and created a lot of interest. Single-sided printed circuit boards (PCBs) are placed on a glass plate, which is heated with IR radiators rated at up to 3000 W. This results in very rapid heating, even when processing large aluminium or ceramic substrates (suitable for sizes between 30 x 30 mm and 300 x 300 mm).
The system is designed for applications where substrates need to be heated quickly to temperatures up to 200°C and without overshoot. LED rework, for example, benefits from high substrate temperatures to facilitate the removal and replacement of individual components from an array.
Two manipulator arms, each with a movement lock, individually carry the placement tool and hot air solder pen to cover the entire working area. Small components can effortlessly be picked up from a dispenser and precisely placed on the PCB with manual alignment. Optimised soldering tools precisely deliver hot air to the solder joints for gentle heating.
At the end of the reflow process, integrated vacuum cups automatically lift the components out of the molten solder. Boards populated on both sides can also be processed. They are supported just above the heating plate using magnetic PCB holders, allowing additional flexibility and freedom to customise processes.
As with all EXPERT systems in the 04.6 family, this version also includes residual solder removal and dispensing. Especially when reworking LEDs, cleaning and re-depositing solder are critical steps, which can be ergonomically handled using this system. The Easy-Solder software and the Autoprofiler support users in establishing, archiving and executing profiles.

A cordless ESD (Electrostatic Discharge) wrist strap does not work by grounding the person in the same way as a traditional wired wrist strap. Instead, it works by reducing or balancing the static charge on your body so that you are less likely to discharge electricity into sensitive electronic components.
