The ERSA TT 500 A is a table-top convection oven for universal reflow jobs in the prototype and small scale production.
The closed heating chamber, the combined convection and quartz emitter heating as well as a separate cooling zone help in-line comparable processes. The integrated microprocessor controls all functions of the TT 500 A including temperature profiles. Apart from 10 preset soldering programs, 10 preset curing parameter sets for the most common applications are included. An additional set of eight profiles can be defined and stored individually.
During process a motorised drawer transfers the PCB into the heating zone. A large double insulated window allows one to survey the soldering process. As the actual temperature and time data is constantly shown, the operator can follow the process on the display.
Upon completion of the reflow and the first cooling process, the drawer transfers the PCB out of the heating zone into the exterior cooling area. Two high power cooling fans then cool the PCB to a reasonable handling temperature.
Two additional thermosensors allow direct temperature measurement on the PCB. Max PCB size is 340 x 410 mm.
The TT 500 A is prepared for nitrogen injection and for connection to a direct air exhaust.

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.
