PCB habka isku guddiga circuit, furaysto hab xiriir
In alaabtii adag iyo qalab, waxaan inta badan isticmaasho hab xiriir siib. Tani "block dhismaha" qaab-dhismeedka aan loo hubiyo in kaliya tayada alaabooyinka wax soo saarka mass, yaraynta kharashka nidaamka, iyo debugging, dayactirka siisaa raaxadeeda. Marka qalabka PCB ka dhammaan / brokens, dadka adeegyada aadan haysan si loo hubiyo qaybaha (ie, hubi Jidka fashilka, il in qaybaha gaarka ah, doonista in ay qaadataa waqti badan), oo kaliya, si loo garto guddiga waa innormal oo markaas waa inaad isla markiiba si aad u bedeli karaan, markii ay u xaliyaan dhibaatada ee suurtagalka ah ugu gaaban, gaabin ka maqnaa muddo ka, loo hagaajiyo isticmaalka qalabka. The guddiga circuit bedelay la fulin karo in waqti ku filan loogu talagalay dayactirka, ka dib markii dayactir qayb ka firaaqada.
1. Daabacidda Board Circuit Socket.
Iyo alaabtooda oo adag iyo qalabka, inta badan hab xiriir this aan u isticmaalno, habkan waa in ay godka ka cidhifka PCB ka dhigi, qayb ka mid ah godka macmalay doonaa sida xajmiga, xidhiidh tilmaamay tirada, meel fog la xidhiidha, sixitaanka dhibcood si ay u qaabeyso qaabka, ugu dambeyntii dhigi PCB la isku aadiyo karaa godka PCB gaar ah.
In the process of manufacture, the part of socket need pated gold surface finish, improve wear resistance, reduce contact resistance. This methos is easy to assemble, and the interchangeability and repair performance is good, is suitable for standardized PCB mass production . The short of this method is the improvement of the cost of printed circuit, has high requirements on soo saarka guddiga circuit daabacay accuary, often due to poor contact of socket because of the osidation orreed aging. In order to improve the reliability of external connections, we often paralel lead the same lead circuit at the same time lead the connection points on the same or bith sides of PCB.
Habka Connection PCB godka inta badan loo isticmaalaa in muiti-loox alaabta qaab-dhismeedka, godka la guddiga circuit ku daabacan ama guddiga / dabaqa hoose ayaa nooca Spring iyo furaysto-in nooca pin.
2. Standard Pin Connection
This method can be used for the external connection of loox wareeg daabacan , expecially in small instruments. Through standard pin to connect two pinted circuit board, these 2 printed circuit boards usually parallel or vertial, it is easy to achiee mass production.
