计算器、遥控器按键不灵的修复方法

计算器、遥控器按键不灵的修复 2009-08-22 16:49 办公常用的计算器由于时间长了按键会很不好用，需用大力气按才能显示数字，家中的电视机、空调、电风扇等常用电器的遥控器按键所发生的类似故障，这些大多是由于某些按键失灵而引起的。这里向大家介绍几种自己动手修理此类故障的方法。 常见的按键结构型式有金属弹簧片 式和导电橡胶式两种。 1.金属弹簧片式按键故障的修复 此类故障往往是因金属片锈蚀、变 形、断裂或面沾满灰尘引起的。锈蚀、 沾灰时，可先将锈蚀部分用刀片轻轻刮 去，再用无水酒精清洗擦拭干净即可，如 严重锈蚀最好更换;弹簧片变形可用镊子 将其整形，恢复原状，若已失去良好的弹 性，最好更换;弹簧片断裂时，也只有更换。金属弹簧片可以自制，选一块厚度相当、弹性良好的黄铜薄片，剪成与原来形状相同大小的，焊上即可，焊接前，一定要将电烙铁插头拔下，用余热焊接，以防静电损坏电路板的集成块。 2.导电橡胶故障的修复 此类故障常常是因橡胶按键上的导电涂层长时间按磨损所致，导致导电涂层阻值的增大，一般是由于表面沾染灰尘或导电涂层脱落。可先用无水酒精清洗，如不能恢复，再用刀片将涂层轻轻刮去薄薄的一层，或者用铅笔(含碳高的)在按键与线路板接触的一面反复摩擦，让碳涂抹道按键上面，增加导电性。仍不能恢复时，只好更换。如果买不到合适的，可以自制替换品:找一块香烟盒中的锡箔，去掉锡Stems, root cause mechanical damage, looping root amputation at the wound to prevent infection. (3) category tree seedlings: a spindle should have a uniform distribution of main branches, branches, trunk diameter above 3.0CM; make trees of broadleaved trees branch height should be relatively consistent, with 3-5 main branch, trunk diameter of not less than 4cm, branch point is not less than 2.5M; coniferous trees with the spindle, there are primary. (4) shrubs class seedlings: tufted type shrubs requirements irrigation bundle full, and main collateral distribution uniform, and main branch number not less than 5 branch, at least has 3 branch above irrigation high reached provides standard; creeping type shrubs requirements at least has 3 branch above main branch reached provides standard length; vine health seedlings, and should points branch uniform, and main article number 5 branch above, and main article diameter 1.0CM above; going it alone type shrubs requirements with trunk, and points branch uniform, base diameter in 2.0CM above; hedge with shrubs requirements irrigation bundle full, and points branch uniform, and dry lower leaves no bare, More than 2 years old. All plants are shrubs should meet the specifications. (5) the solitary trees should be selected single planting ornamental tree is beautiful, high ornamental value of individual plants. (6) design should be selected when the bushes planted plant specifications, flowering shrubs such as rhododendron plants should select color uniform varieties, planting interval and density. 4, seedling planting project plants should be located according to the drawings, and with reference to the national standard and suitable to avoid lines, planting pits should be greater than the minimum thickness requirements, planting soil backfill compaction in layers to ensure that plants are firmly rooted in the ground, supported by large-size seedlingshe primary analysis of soil physical and chemical properties, such as pests, disinfection, pest control in advance. Garden plant growth by required of minimum planting soil thickness should meet Xia table (construction figure Shang indicate of except) vegetation type herb flower lawn to was small shrubs big shrubs shallow root trees deep root trees soil thickness 30 (CM) 30 (CM) 45 (CM) 60 (CM) 90 (CM) 120 (CM) planting soil should selection for plant growth of selective soil, as humic acid soil, and lawn fertilizer, and peat soil, and pH 5.5~7.0, humidity 30~70%, completely loose, Lawn planting soil roughness (soil surface should be lower than teeth pond 2~5cm). 2, planting garden of foundation engineering projects from planning to the construction stage, focus on after completion of landscaping, the overall goal is to create a good living environment for plants, create a garden and green space. Plant engineering of the project was to create the basis for plant growth, soil, it can be said is the garden project, is one of the most important works. Also planted phase of this project must be carried out by the local soil improvement project. 3, seedling selection requirements: (1) engineering seedling selection of cooked goods, provisions relating to plant size. Plant procurement specifications can be large, so as to achieve ecological effect in a short time. Seedlings should have ... Strong, lush, Crown-shaped full, normal color, root system, pest and disease-free. (2) the project should have growth robust, lush, Crown-shaped full, normal color, root system, pest and disease-free. 箔表面的薄薄的一层纸后，剪成与原来相同的形状，再在锡箔面上及原导电橡胶处涂上一层万能胶，待干后，把铝箔贴在导电橡胶上，压实后即可使用。 3.线路板上导电涂层的故障 线路板上的导电涂层磨损时，用上述几种一般不能很好地修复，即使剪块与线路上触点相同形状的金属片，由于线路板上的导电线条较细，剪成的金属片易变形，且不能很好地固定，虽暂时能用，过不了多久故障又会出现。这里介绍一种比较好的办法能将其迅速修复。 将一节废旧的1号干电池砸开，取出碳棒，把碳棒刮干净，用细钢锉在碳棒上锉取一定量的碳粉，越细越好，一般一个触点仅需一粒蚕豆大小的量即可。再将碳粉与适量木工用的白乳胶(或万能胶，但不如用白乳胶操作方便)混合、搅匀成浆糊状，用小号钟表起子(或牙签)边蘸取边涂到线路板的导电线条上，动作要快，防止先涂的已干硬，不能与后面的很好粘接，涂时要细心，尽量不要与邻近的线路相连。待碳粉糊稍干不沾手时，用手压平，起子整形，如不慎两条线路短路，待碳粉糊干透后用刀片将相连处轻轻刮去即可使用。 此办法简单易行，比用导电墨水(甲苯、银粉等化学原料配制)取材容易，操作简单，且使用效果良好 空调遥控器按键不灵的修复(原创，转载请注明出处) 电子产品维修 2009-06-11 21:54:49 阅读216 评论0 字号:大中小 遥控器放了很久，结果就是一些按键正常，另外一些按键不正常，按下去没反应。 当时拿到这个觉得好奇怪，空调的遥控器和电子词典不一样，用的不是很频繁，一般不会出现按键不灵的问。而且这不灵 的按键不是最常用的，是随机的。 如果时间久了，导电橡胶老化，就会是绝大多数不能用了。 所以可以推断出这个不是那种普通的按键不灵的问题。具体是什么原因，现在还不知道，要拆开才知道。 LG的遥控器，卡扣结构，比较紧，要废点力气才可以。 Stems, root cause mechanical damage, looping root amputation at the wound to prevent infection.
