目前的VCD机之中.较为常见的则有以下二个类型的解压板:一是单一的解压板部分;二是解压板和伺服电路做在一起的(简称为“二合一板”)。随着电路的设计技术的成熟,电路板的体积越做越小,电路的元件密度也是越来越密,这给我们的检修上作造成了不少不便和难度,也提出新的要求,只要我们好好地利用,检修的工作并不是十分困难。就笔者的经验来说,在VCD机的检修之中,激光头的损坏是占很大的比例,其次足以伺服板的故障和解压板的故障(约占20％).然而,正是这20％的故障,难倒了不少 The current VCD machines are more common there are the following two types of decompression board: First, a single decompression board part; the second is the decompression board and the servo circuit together (referred to as “combo”). With the maturity of the circuit design technology, the smaller the circuit board volume, the circuit component density is getting more and more dense, which caused a lot of inconvenience and difficulty to our maintenance, but also put forward new requirements, as long as We make good use of maintenance work is not very difficult. As far as the author’s experience is concerned, the damage to the laser head accounts for a large proportion of the overhaul of the VCD machine, and secondly, the failure of the servo board and the decompression board (about 20%). However, it is this 20 % Of failures, stumped a lot
