Point-to-point construction is a non-automated method of construction of electronics circuits widely used before the use of printed circuit boards (PCBs) and automated assembly gradually became widespread following their introduction in the 1950s. Circuits using thermionic valves (vacuum tubes) were relatively large, relatively simple (the number of large, hot, expensive devices which needed replacing was minimised), and used large sockets, all of which made the PCB less obviously advantageous than with later complex semiconductor circuits. Point-to-point construction is still widespread in power electronics where components are bulky and serviceability is a consideration, and to construct prototype equipment with few or heavy electronic components. A common practice, especially in older p

rdfs:comment	空中配線（くうちゅうはいせん、英語：Point-to-point construction）とは、電気部品同士をリード線で接続して電気回路を構成する配線技法のこと。プリント基板技術が登場してからは一般的には利用されなくなったが、試作電子回路の製作やパワーエレクトロニクスの分野、プリント基板表面の微小漏洩電流をも嫌う分野などでは現在でも利用される技法である。 (ja) La costruzione punto a punto (in inglese point-to-point construction) è la tecnologia di costruzione dei circuiti elettronici prima degli anni cinquanta, quando fu soppiantata dalla tecnologia a fori passanti (through-hole). Questa tecnologia è ancora utilizzata per costruire dispositivi con pochi componenti elettronici o con componenti pesanti. Questo tipo di cablaggio "in aria" è stato ripreso da alcuni piccoli costruttori per la circuitazione di amplificatori e altre apparecchiature audio di fascia alta (hi-end), impieganti tubi termoionici. (it) Навісний монтаж — спосіб монтажу електронних схем, при якому розташовані на ізолюючому шасі радіоелементи з'єднуються один з одним провідниками або безпосередньо своїми виводами. (uk) Навесной монта́ж — способ электронных схем, при котором расположенные на изолирующем шасси радиоэлементы соединяются друг с другом проводами или непосредственно выводами. Недостаток навесного монтажа — он плохо поддаётся автоматизации и обычно выполняется монтажниками вручную. В настоящее время в массовом производстве применяется редко и обычно только при монтаже крупногабаритных деталей. (ru) Montáž mezi spojovací body je manuální způsob montáže elektronických zařízení, používaný před hromadným zavedením desek plošných spojů a automatizované montáže v 50. letech 20. století. Tehdy běžná zařízení využívající vakuové elektronky byla rozměrná, s malým počtem součástek. Použity byly dosti velké objímky elektronek s vývody ve formě kolíků nebo pájecích oček. Také další používané součástky: mechanické přepínače, vzduchové ladicí kondenzátory, transformátory a sady vysokofrekvenčních cívek byly přednostně konstruovány s vývody v podobě pájecích oček. Tyto vývody (pájecí očka, kolíky) posloužily jako spojovací body pro připojení drobnějších součástek pájením. Rezistory a svitkové kondenzátory se připojovaly přímo na spojovací body. Stejným způsobem byly připojeny i holé nebo izolované (cs) Eine Lötleiste ist ein elektromechanisches Bauteil, das aus einem isolierenden Trägermaterial (beispielsweise aus Hartpapier) und mehreren – meist paarig angeordneten – Lötösen besteht. Die Lötleiste dient gleichzeitig als mechanischer Stützpunkt für die angelöteten Elektronikbauelemente – wie beispielsweise Widerstände, Kondensatoren, Spulen und Transistoren. Weiterhin stellen diese Leisten die elektrische Lötverbindung her. Bei den angelöteten Bauelementen handelte es sich in der Vergangenheit meist um leichte Bauelemente, während schwerere Bauelemente in der Vergangenheit häufig mittels Schellen direkt mit dem Gerät mechanisch verbunden waren und die elektrische Verbindung dann zu diesen Bauelementen meist über Leitungen erfolgt ist.

A common practice, especially in older p (en) Een punt-naar-puntconstructie is een constructiemethode, die binnen de elektronicabouw wordt gebruikt. Bij deze constructiemethode worden de componenten, van het type through-hole waar meestal al bevestigingspunten van afdoende lengte, van koperdraad aan zitten, direct aan elkaar gesoldeerd, dus zonder van een printplaat of experimenteerprint gebruik te maken. Met de komst van ontwerpprogramma's voor printplaten, die vaak gratis zijn, kunnen schakelingen eenvoudiger worden getest en zijn punt-naar-puntschakelingen een zeldzaamheid geworden. De methode is storingsgevoelig. (nl)
