薄型电子产品,如计算器,电子笔记本和语音时钟等小电器,结构大致有三种形式:稍厚的有螺丝固定,但螺丝有时隐闭在电池盒中或铭牌后面;大多数为塑料盒带倒扣的紧配合,拆卸时用指甲或包裹塑料胶带的螺丝刀顺盒缝用力前推,使倒扣脱出;特薄的太阳能卡片或电子计算机和卡片式电子笔记本,看不到丝毫组合痕迹,让人无从下手。图1是这类产品的结构。最上层是带有导电薄膜的面板,薄如一张电话磁卡,硬度、韧性特殊。中间一片印制板,上面为印制开关触点,背面是元件和大规模集成
Thin electronic products, such as calculators, electronic notebooks and voice clocks, come in three configurations: a thicker one with a screw, but sometimes the screw is hidden in the battery compartment or behind the nameplate; most are plastic ones with backslashes Tight fit, remove the nail or plastic wrap wrapped with a screwdriver along the box before pushing forcefully, so that the inverted deduction; thin solar card or electronic computer and card-type electronic notebook, can not see the slightest combination of traces, people no way Start. Figure 1 shows the structure of this product. The top is a panel with a conductive film, thin as a phone card, hardness, toughness special. The middle of a printed circuit board, above the printed switch contacts, the back of the components and large-scale integration
