LEDtronics’ Long-Lasting, High Shock and Vibration Resistant LEDs Bring Light to Semiautomatic Screener and Pick-and-Place Machines

There’s an illumination dilemma in some machines at electronics factories where surface mount technology prevails.

One of these is the screener, a semiautomatic machine where solder paste is added to printed circuit boards (PCB) in a process very much like that used with old silk-print technology. Putting observational light on the PC boards from outside of the screener machine is difficult as the operator’s head will cast an interfering shadow and hinder light from entering the machine. Using a few LEDtronics’ Super-Intensity Sealed Backlight LED Modules (LEDtronics Part Number STP301S-2x2-2CW-012) solves the problem. Now light can flow inside the machine, and the operator can easily inspect the surface of the PCB as it passes by to verify that the solder paste is properly applied to each PCB surface.

The pick-and-place machine is another common automated device that has the same lighting challenge. Shadows prevent the operator from observing whether the pick-and-place head is correctly positioning the components on the solder pads of the printed circuit board. The problem is solved with the installation of six LEDtronics’ Super-Intensity Sealed Backlight Modules (Part Number STP301S-2x2-2CW-012). The Cool White LED light provides excellent optimal viewing for the operator, who no longer has to remove the entire PCB from out of the machine for inspection.
