CD-ROM laser head cleaning method found that CD-ROM drive capacity decreased, and make sure that is caused due to the laser head is dirty, has decided to clean the laser head, the best from simple to complex in three steps. The first step in cleaning the laser head and the upper surface of the focusing lens cleaning with a cotton swab dipped in a little clear water, gently wipe it. Because the lens surfaces to dust, dirt, and most cases, failure can be ruled out. If invalid, the second step can be considered "immersion" of the optical path of the laser head cleaning. The first laser head into the detergent solution to soak and then into the water to soak, and let the water to the dirt away. "Immersion" specific applications "newsletter" has been introduced. green laser pointer can create five different laser effects.
This is a relatively safe method of cleaning. Immersion laser head needs to be taken down, static protection should be prepared as shown in Figure 1, metal trap clamped electrostatic protection film cable plug. If there is no protective folder, you should short circuit short-circuit solder joints on cable plug with the waste heat of the soldering iron. To Italy: the circuit work is to be restored, it should then disconnect. If you still does not work, please do not rush to adjust the transmit power of the laser tube, I discovered the power regulation, as many as one year, at least a month, the laser tube completely aging. Among which may be immersion cleaning is inadequately mistakenly power tune of the General Assembly to promote the laser tube to premature aging. Balance, as the laser head to do a cleaning. Or the user can get the 5 in 1 green laser pointer .
The third step is to pry open the laser head, a thorough cleaning. The laser head is constituted by several parts, in fact, it is a "component". This component is characterized by small size, compact structure, and each of the parts are very delicate, even if it is minor damage, small deformation, the Ministry will give the CD-ROM drive servo control adverse effects. Therefore, in the third step prior to cleaning. Should be carefully observed and analyzed to clarify the structural relationship to work out to pry open the steps to ensure safety. In this paper, the CDR the-OP24XT CD-ROM drive, for example, to analyze the structural relationships and steps to pry open. Figure 2 for the CD-ROM laser head to remove the front shield. The most striking part is the Blu-ray focusing lens, which is embedded in the black plastic on the lens bracket. It is to improve the sales volume of green laser pointer .
The bracket are focusing coil and tracking coil, the water was a flat installation, set of heart magnets focusing coil; vertical installation of the tracking coil. 4 elastic alloy wire (front only to see the above two), one end welded to the fixed lens bracket with a small circuit board (Figure 2 alloy wire F end), and the lens bracket hold in suspension, when subject to external force. Bracket and lens of the lens, focusing coil and tracking coil will move together. Four elastic alloy wire is one of the most sensitive parts in the CD-ROM drive servo control system, which damage will cause the evil consequences, and therefore need to be careful throughout the process. It is according to the market expectation of green laser pointer .
The other end of the four elastic alloy wire is soldered into a small circuit board, this board is fixed to the core base. 4 sets of gold also plays a conductive role: the above two tracking coil power supply; the following two to the focusing coil power supply. The core base is a fixed basis of the important parts, it is iron, rigid, and can withstand a strong external force. The core base and the fixed mode of the laser head housing first, from the mosaic of lugs and grooves, the two rely on a fixed screw on the back of the case, as shown in Figure 3. Analysis based on these observations, worked out to pry open the laser head is as follows: Unscrew the screws of the tablet, remove the tablet, so that the film cable to relax. It is to take up market shares of green laser .
