Provided is a barrel support device for supporting a lens barrel. The barrel support device may include a guide frame configured to laterally support the lens barrel and tilt with the lens barrel, a rotation guide on a first end of the guide frame, the rotation guide being ring shaped and configured attach the lens barrel to the guide frame, and a ring-shaped tilting frame configured to support a second end of the guide frame and tilt the guide frame, wherein the guide frame, the rotation guide, and the tilting frame are configured to allow the lens barrel to pass therethrough.

Lens barrel support device and maskless exposure apparatus having the same

Example embodiments are directed to a maskless exposure apparatus that generates and/or corrects exposure data using at least one information of intensity information, central position information, focus information, and/or shape information of a plurality of beams acquired using a measurement optical unit, and a control method thereof. The maskless exposure apparatus includes the measurement optical unit including a photo sensor and an image sensor, and a control unit configured to generate and/or correct the exposure data using the information acquired by the measurement optical unit.

Maskless exposure apparatus having measurement optical unit to measure depths of focus of a plurality of beams and control method thereof

A method to compress exposure data may include converting image data into a plurality of exposure data, generating new exposure data by combining part of the plurality of exposure data or by excluding part of the plurality of exposure data, and compressing the new exposure data. An exposure apparatus may include a conversion unit that converts image data into a plurality of exposure data, a control unit that generates new exposure data by combining part of the plurality of exposure data or by excluding part of the plurality of exposure data, and a compression unit that compresses the new exposure data.

Exposure apparatuses and methods to compress exposure data

Disclosed herein is a method for fabricating a printed circuit board assembly by adhering an element to a printed circuit board without using any solder. The printed circuit board may be fabricated by sequentially applying a conductor-containing first ink and an insulator-containing second ink onto a base substrate by ink-jet printing to form a printed circuit board, mounting an element on the printed circuit board such that an electrode of the element contacts a conductive layer and curing the conductive layer at a high temperature.
