摘要： Vias (12) with substantially straight walls and no undercut regiosn at the bottom can be formed in a laminated substrate (10) by combining percussion drilling and trepanning drilling techniques and using different types of lasers. The top copper foil (13) of the laminated substrate (10) is first cut through, along the boundary of the via (12) to be drilled, to form a peripheral channel. This is accomplised by trepanning drilling using a UV laser (21). Then, an IR laser is applied to ablate the dielectric material (14) inside the via (12). During this step, a cutoff copper piece (40), which remains in the central regions of the via (12) after the trepanning drilling, will be removed as well. The IR laser reflects off a copper capture pad (131) at the bottom of the via (12), effectively cleaning the capture pad (131) surface for later plating processes.

摘要： This invention applies to the use of shaped beams of laser radiation for increasing the maximum speed of tools used to laser drill microvia holes in PCB's, PWB's and other electrical circuit packages. With an annular spatial intensity distribution, the maximum speed can be increased several fold from machines which do not incorporate such laser beam shaping. Different hole diameters on a one device can be programmed using a set of ring beam shaping elements incorporated into a single transmissive mask element whose lateral position when placed in the beam is computer-controlled.

摘要： In a system which interrupts the infeed signal generated by a CNC (1) machine drive signals are applied to at least an RPM Control Electronics Module (3) to drive the rotation of a cutting tool (10) and the infeed drive motor electronics (7). The frequency is user selectable and the frequency used to eliminate or minimize chip formation is dependent upon the material being drilled, the infeed rate, the RPM of the tool (10), and the diameter and point geometry of the tool (10) so adjustment by the machine operator is required. The interrupted or chopped signal causes the downward motion of the RPM motor (5) to be interrupted in conformance with the frequency generated to cut forming spiral chips.

摘要： A laser based, noncontacting measurement instrument particularly adapted for the printed circuit board drilling industry is disclosed. The instrument accurately measures drill diameter, runout, and tip position under actual operating conditions. A laser beam is focused in space and the amount of light occluded by the drill bit as the bit is passed through the beam is sensed by a detector. Diameter, runout, and tip position are calculated by measuring the amount of occlusion, monitoring the angular orientation of the rotating drill; and correlating the amount of light occlusion to the angular orientation of the drill. The instrument automatically compensates for dust and debris in the optical path.

摘要： A non-contact, laser detection system for detecting the extended state of an object in continuous motion such as a drill bit. For detecting the state of sufficient or insufficient flute length of the drill bit, the drill bit is moved in relation to the laser detection system until energy reflected from the tip of the drill bit is detected. Then, the drill bit is moved in relation to the laser detection system a pre-selected distance from the point at which the tip was initially detected, to a second point where the energy reflected from the drill bit is analyzed by a computer to determine if the laser is still incident on the fluted section of the drill bit. If the computer determines that the laser is still incident on the fluted section, then the flute length of the drill bit is at least as long as the pre-selected distance.

摘要： A non-contact, laser detection system for detecting the extended state of an object in continuous motion such as a drill bit. In the drill bit embodiment, the detected states are clean, clogged and broken. In the laser detection system (200), a first signal, indicative of energy reflected from the surface of the drill bit, is digitized and compared to a first threshold. A second signal, indicative of amplified energy reflected from the drill bit, is digitized and compared to a second threshold. The digital signals are analyzed by a computer (202) to detect the state of the drill bit.
