F0031241023印刷电路板，又称印制电路板，印刷线路板，常使用英文缩写PCB（Printed circuit board），是重要的电子部件，是电子元件的支撑体，是电子元器件线路连接的提供者。由于它是采用电子印刷技术制作的，故被称为“印刷”电路板。在印制电路板出现之前，电子元件之间的互连都是依靠电线直接连接而组成完整的线路。现在，电路面板只是作为有效的实验工具而存在，而印刷电路板在电子工业中已经成了占据了绝对统治的地位。20世纪初，人们为了简化电子机器的制作，减少电子零件间的配线，降低制作成本等优点，于是开始钻研以印刷的方式取代配线的方法。

F0031241023三十年间，不断有工程师提出在绝缘的基板上加以金属导体作配线。而最成功的是1925年，美国的Charles Ducas 在绝缘的基板上印刷出线路图案，再以电镀的方式，成功建立导体作配线。 直至1936年，奥地利人保罗·爱斯勒（Paul Eisler）在英国发表了箔膜技术，他在一个收音机装置内采用了印刷电路板；而在日本，宫本喜之助以喷附配线法“メタリコン法吹着配线方法(特许119384号)”成功申请专利。

F0031241023而两者中Paul Eisler 的方法与现今的印刷电路板最为相似，这类做法称为减去法，是把不需要的金属除去；而Charles Ducas、宫本喜之助的做法是只加上所需的配线，称为加成法。虽然如此，但因为当时的电子零件发热量大，两者的基板也难以配合使用，以致未有正式的实用作，不过也使印刷电路技术更进一步。

F0031241023 Printed circuit board, also known as printed circuit board and printed circuit board, often uses the English abbreviation PCB(Printed circuit board). It is an important electronic component, a supporter of electronic components and a provider of circuit connection of electronic components. Because it is made by electronic printing technology, it is called “printed” circuit board. Before the appearance of printed circuit boards, the interconnection between electronic components depended on the direct connection of wires to form a complete circuit. Now, the circuit panel only exists as an effective experimental tool, while the printed circuit board has become an absolute dominant position in the electronic industry. At the beginning of 20th century, in order to simplify the manufacture of electronic machines, reduce the wiring between electronic parts, and reduce the manufacturing cost, people began to study the method of replacing wiring by printing.

F0031241023 In the past 30 years, engineers have been proposing to add metal conductors to insulated substrates for wiring. The most successful one was in 1925, when Charles Ducas of the United States printed a circuit pattern on an insulating substrate, and then successfully established conductors for wiring by electroplating. Until 1936, Paul Eisler, an Austrian, published the foil film technology in England, and he used a printed circuit board in a radio device; In Japan, however, Hayuke Miyamoto successfully applied for a patent by spraying wiring method “Blowing wiring method (Patent No.119384)”.

F0031241023 Paul Eisler’s method is the most similar to that of today’s printed circuit boards. This kind of method is called subtraction method, which removes unnecessary metals. The practice of Charles Ducas and Miyamoto Sukeyoshi is to add only the necessary wiring, which is called additive process. Even so, because of the high calorific value of electronic parts at that time, the substrates of the two parts were difficult to be used together, so that there was no formal practical work, but it also made the printed circuit technology go further.
