Abstract: In a method for patterning a reel-to-reel strip in an automatic manufacturing process, a reel-to-reel strip is stuck onto a support plate having a low-tack adhesive. A laser beam is used to pattern the reel-to-reel strip. Carbon residues and/or cut pieces generated during a process of patterning the reel-to-reel strip are stuck on the support plate having the low-tack adhesive. Therefore, the carbon residues and/or the cut pieces will not fall down to other parts of the reel-to-reel strips during the automatic manufacturing process. Thus, it does not need to remove the carbon residues and/or the cut pieces from the reel-to-reel strips.

Abstract: A method for positioning a reel-to-reel flexible board in an automatic manufacturing process uses an optical sensor to detect a first edge and a second edge of the reel-to-reel flexible board and obtain first x-coordinate data, second x-coordinate data and y-coordinate data. A set of positioning holes is precisely formed using the obtained coordinate data. The positioning holes are used to define a starting point of a next work area to prevent the gap between the two work areas from being larger or smaller than a predetermined value. Because micro-via forming and image transfer procedures are applied on the reel-to-reel flexible board using the coordination data, shift and offset can be prevented.

Abstract: A ratchet tool includes a handle, a tooling sleeve, a first pawl, a first elastic member, a second pawl, a second elastic member, a retaining ring, and a dialer. The outer circumference of the tooling sleeve received in the handle is disposed with teeth. The pawls and the elastic members are contained in the handle. Each of the pawls is disposed with teeth and a post. The retaining ring covers up the pawls and the elastic members and is secured to the handle. The dialer is pivoted to the retaining ring to change work direction of the tooling sleeve by moving the pawls as driven by the posts linked to the dialer when the dialer is turned to either side.

Abstract: A ratchet structure of a wrench includes a handle, a socket, a first detent, a first elastic element, a second detent, a second elastic element, a lid and a knob. The outer periphery of the socket is formed with gear teeth. The socket is accommodated in the handle. The first and second detents and the first and second elastic elements are also accommodated in the handle, respectively. Each of the first and second detents is provided with gear teeth and a stud. The lid is secured to the handle and covers the detents and the elastic elements. The knob is pivotally connected to the handle. By turning the knob, the studs are linked to turn to change the turning direction of the socket.
