The processing chamber includes a wafer stage being operable to secure and move a wafer, and a laser-charged particles interaction module that further includes a laser source to generate a first laser beam; a beam splitter configured to split the first laser beam into a second laser beam and a third laser beam; and a mirror configured to reflect the third laser beam such that the third laser beam is redirected to intersect with the second laser beam to form a laser interference pattern at a path of the charged particles, and wherein the laser interference pattern modulates the charged particles by in a micron-zone mode for processing the wafer using the modulated charged particles.

An apparatus and a method for powder bed fusion additive manufacturing involve a multiple-chamber design achieving a high efficiency and throughput. The multiple-chamber design features concurrent printing of one or more print jobs inside one or more build chambers, side removals of printed objects from build chambers allowing quick exchanges of powdered materials, and capabilities of elevated process temperature controls of build chambers and post processing heat treatments of printed objects. The multiple-chamber design also includes a height-adjustable optical assembly in combination with a fixed build platform method suitable for large and heavy printed objects. A side removal mechanism of the build chambers of the apparatus improves handling and efficiency for printing large and heavy objects. Use of a wide range of sensors in the apparatus and by the method allows various feedback to improve quality, manufacturing throughput, and energy efficiency.

A device for removing a defective electronic component from a circuit board includes a vacuum suction nozzle, a laser beam emitter and an infrared temperature sensor. The vacuum suction nozzle has a suction opening at which suction is generated. The suction opening is dimensioned to be larger than the defective electronic component. The laser beam emitter is oriented so as to emit a laser beam out the suction opening towards the electronic component on the circuit board. The temperature sensor measures the temperature of the electronic component based on infrared radiation emitted from around the electronic component. A method for removing the defective electronic component from the circuit board includes positioning the suction opening over the electronic component and directing the laser beam through the suction opening and onto the electronic component so as to heat and detach the electronic component, which is then sucked into the vacuum suction nozzle.
