PCB dera bolodi interconnection njira: pulagi njira kugwirizana
Mu zida zovuta ndi zida, ife amagwiritsa ntchito njira pulagi kugwirizana. Izi "nyumba chipika" kapangidwe osati kuonetsetsa amasokoneza kuŵeta, kuchepetsa mtengo wa dongosolo, ndi debugging, kukonza imapereka mayiko. Pamene zida pcb ndithu / brokens, utumiki anthu alibe kuchepetsa zigawo (ie, fufuzani chifukwa cha kulephera kwa anthu angati ku zigawo zenizeni, kufuna kuti kumafunika nthawi), basi kudziwa bolodi ndi innormal ndiyeno inu athanso m'malo izo, nthawi kuthetsa vutolo mu yayifupi zotheka, kufupikitsa downtime, patsogolo magwiritsidwe zida. The m'malo gulu dera angathe kuchitidwa mu nthawi yokwanira kukonza, pambuyo kukonza monga gawo yopuma.
1. Kusindikizidwa Dera Board Socket.
Ndi zida zovuta equipments, nthawi zambiri ntchito njira kugwirizana, njira imeneyi ndi kupanga zitsulo m'mphepete mwa PCB, gawo la zitsulo adzakhala chopangidwa monga kukula, kugwirizana anatchulapo chiwerengero, kugwirizana mtunda, kusonyeza mfundo kupanga kamangidwe, potsiriza kupanga PCB akhoza chikufanana ndi PCB zitsulo wapadera.
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 kusindikizidwa dera bolodi kupanga 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 zitsulo mgwirizano njira kawirikawiri amagwiritsidwa ntchito muiti-matabwa dongosolo mankhwala, zitsulo ndi kusindikizidwa dera bolodi kapena pansi / pansi thabwa ali Spring mtundu ndi pulagi-mu mtundu pini.
2. Standard Pin Kulumikiza
This method can be used for the external connection of matabwa kusindikizidwa dera , 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.
