PCB Modh ciorcad idirnaisc: breiseán modh nasctha
I uirlisí agus trealamh casta, ní mór dúinn a úsáid go minic ar an modh nasctha breiseán. Seo "bloc tógála" déanmhas ní a chinntiú ach an caighdeán na dtáirgí olltáirgeadh, ag laghdú an costas an chórais, agus chun debugging, cuireann cothabháil áise. Nuair a theipeann ar an trealamh PCB / brokens, ní dhéanann na daoine seirbhíse a sheiceáil na comhpháirteanna (is é sin, seiceáil an cúis leis an teip, foinse do na comhpháirteanna sonracha, a thógann go mbeidh go leor ama), ach a chinneadh a bhfuil bord innormal agus ansin is féidir leat láithreach a chur ina ionad, am chun an fhadhb a réiteach sa giorra is féidir, ghiorrú an downtime, feabhas a chur ar an úsáid a bhaintear as trealamh. Is féidir leis an mbord chuaird in ionad a chur i gcrích in am cuimsithí do dheisiú, tar éis a dheisiú mar chuid spártha.
1. Clóbhuailte Chuarda Bord Socket.
Le uirlisí agus trealamh casta, ní mór dúinn a úsáid go minic ar an mbealach dtaca leis sin, tá an modh soicéad a dhéanamh ó imeall PCB, beidh an chuid den soicéad mhonaraítear mar an méid, pointí nasc uimhir, achar dtaca leis sin, pointí marcáil a dhearadh an leagan amach, ar deireadh Is féidir le PCB a dhéanamh a mheaitseáil le Soicéad PCB speisialta.
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 déantúsaíochta clóite ciorcad 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.
Tá Modh Ceangal PCB Soicéad úsáidtear go minic i muiti-boird Táirgí struchtúr, soicéad le bord chuaird clóite nó bord / urlár bun cineál Earraigh agus plug-in chineál bioráin.
2. Caighdeán PIN Ceangal
This method can be used for the external connection of cláir chiorcad clóite , 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.
