PCB oa potoloho boto interconnection mokhoa: plug mokhoa mabapi
Ka liletsa tse rarahaneng le thepa, hangata re sebelisa mokhoa polaka mabapi. Sena "a thepa ea mohaho le literata" sebopeho sa feela netefatsa boleng ba lihlahisoa boima tlhahiso, fokotsa litšenyehelo ea tsamaiso, 'me bakeng sa debugging, tokiso e fana ka bebofalletsa. Ha thepa pcb hlōleha / brokens, tšebeletso batho ba u se ke ua lokela ho hlahloba metsoako e (khr, hlahloba sesosa sa ho hlōleha ho, mohloli ho dikarolo itseng, thato ea hore nka nako e ngata), feela ho bona hore tseo boto e innormal ebe o ka hang-hang ho nkela sebaka, nako ea ho rarolla bothata boo ka lekgutshwane khoneha, khutsufatsa le nako ea phomolo, ntlafatsa tshebediso ya thepa. The nkeloa sebaka boto oa potoloho ka ho phethahatsoa ka nako e lekaneng bakeng sa ho lokisa, ka mor'a ho lokisa ka karolo fokoletsoe.
1. Printwa Potoloho Board Socket.
Ka liletsa tse rarahaneng le equipments, hangata re sebelisa tsela ena mabapi, mokhoa ona ke ho etsa hore soketeng ho tloha moeling oa PCB, e leng karolo ea soketeng tla etsoa ka boholo, mabapi bontša palo, mabapi hole, tšoaea lintlha tse ho meralo le moralo, qetellong etsa PCB ka matched le PCB soketeng khethehileng.
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 hatisitsoeng oa potoloho boto difeme 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.
PCB soketeng amana mokhoa atisa ho sebelisa ka muiti-mapolanka sebopeho dihlahiswa, soketeng le hatisitsoeng oa potoloho boto kapa tlase / mokatong boto o Spring mofuta le plug-in mofuta Pin.
2. Standard Pin amana
This method can be used for the external connection of mapolanka hatisitsoeng oa potoloho , 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.
