1: Isisekelo sokukhetha ububanzi bocingo oluphrintiwe: Ububanzi obuncane bocingo oluphrintiwe luhlobene nokugeleza kwamanje ngocingo: Ukuphikiswa komugqa kukhulu kakhulu, futhi ukumelana kocingo kukhulu kakhulu, futhi i-voltage yehla kulayini ikhulu, okuthinta ukusebenza komjikelezo. Ububanzi be-Line bubanzi kakhulu, ukuqina kwe-wiring akuphezulu, indawo yebhodi iyanda, ngaphezu kokwanda kwezindleko, akusilungele ukwenza okuncane. Uma umthwalo wamanje ubalwa njenge-20A / MM2, lapho ububanzi be-foil ye-Copper Clad u-0,5 mm, (imvamisa kakhulu), umthwalo wamanje we-1mm (cishe ama-14 mm (40-100 mm (40-100 MM) angahlangabezana nezidingo zohlelo lokusebenza olujwayelekile. Umhlabathi we-wire kanye nokunikezwa kwamandla ebhodini lemishini ephezulu kungandiswa ngokufanele ngokuya ngosayizi wamandla. Emibuthanweni yedijithali ephansi, ukuze uthuthukise ukuqina kwe-wiring, ububanzi obuncane belayini bunganeliswa ngokuthatha u-0.254-1.27mm (10-15mil). Ebhodini elifanayo lesekethe, intambo yamandla. Intambo yomhlabathi iyaqina kunocingo lwesiginali.

2: Ukuhlukaniswa komugqa: Uma kungu-1.5mm (cishe ama-60 mil), ukumelana nokufakelwa kwezindawo eziphakathi kwemigqa kungafinyelela ku-100 njenge-1.0-1.5 mm (40-60 Mil). Emibuthanweni ye-voltage ephansi, efana nezinhlelo zesifunda zedijithali, akudingekile ukubheka i-voltage ye-breakdown, njengoba inqubo ende yokukhiqiza ivumela, ingaba mincane kakhulu.

I-3: Pad: Okwe-1 / 8W Provocation, i-Pad Lead Director i-28mil yanele, futhi ngo-1/2 w, ububanzi bamakhangi obukhulu bukhulu, futhi ububanzi bendandatho ye-PORTS bukhulu kakhulu, okuphumela ekunciphiseni okunama-pad. Kulula ukuwa, umgodi wokuhola muncane kakhulu, futhi ukubekwa kwengxenye kunzima.

4: Dweba umngcele wesifunda: ibanga elifushane kakhulu phakathi komugqa womngcele kanye ne-pad ye-PIN yengxenye akunakuba ngaphansi kwe-2mm, (Ngokuvamile i-5mm inengqondo kakhulu) ngenye indlela, kunzima ukusika okuqukethwe.

I-5: Umgomo wesakhiwo sengxenye: A: Isimiso esijwayelekile: Ku-PCB Design, uma kukhona amasekethe edijithali kanye nemibuthano ye-analog ohlelweni lokujikeleza. Kanye nemibuthano ephakeme yamanje, kufanele ibekwe ngokwahlukana ukuze kuncishiswe ukuhlangana phakathi kwezinhlelo. Ngohlobo olufanayo lwesifunda, izakhi zifakwa emabhuloki nasekwangweni ngokuya ngokuqondiswa kokugeleza kanye nokusebenza.

I-6: Iyunithi yokufaka isiginali yokufaka, into yokuphuma yesiginali yokuphuma kufanele ibe seduze kwe-Circuit Board Side, yenza umugqa wesiginali wokufaka nowokukhipha amafushane ngangokunokwenzeka, ukuze unciphise ukuphazanyiswa kokufaka nokukhipha.

7: Ukuqondiswa Kwezingxenye: Izakhi zingahlelwa kuphela ngezindlela ezimbili, ezivundlile nasemnyeni. Ngaphandle kwalokho, ama-plug-ins awavunyelwe.

8: Isikhala se-element. Amabhodi aphakathi aphakathi, izikhala phakathi kwezingxenye ezincane ezifana nabamelana namandla aphansi, ama-capacitors, ama-diodes, nezinye izinto ezi-discrete zihlobene nenqubo ye-plug-in kanye ne-welding. Ngesikhathi sokuthengisa amagagasi, ukuhlukaniswa kwengxenye kwengxenye kungaba ngu-50-100mil (1.27-2.54mm). Kukhulu, njengokuthatha i-100mil, i-Chip ye-Chip ehlanganisiwe, ukuhlukaniswa kwengxenye yengxenye ngokuvamile 100-150mil.

9: Lapho umehluko ongaba khona phakathi kwezakhi kukhulu, ukuhlukaniswa kwezikhala phakathi kwezakhi kufanele kube ezinkulu ngokwanele ukuvikela ukukhishwa.

10: E-IC, i-capacitor yokukhohlisa kufanele isondelene ne-PIN ye-Power Supply Supply Gip ye-Chip. Ngaphandle kwalokho, umphumela wokuhlunga uzoba mubi kakhulu. Kumasekethe edijithali, ukuze kuqinisekiswe ukusebenza okuthembekile kwezinhlelo zesifunda sedijithali, ama-IC Demoupling Capacitors abekwe phakathi kokuhlinzekwa kwamandla kanye ne-Chip ngayinye ehlanganisiwe ye-Digital Ama-capacitors wokuwa ajwayele ukusebenzisa ama-capacitor we-ceramic chip anomthamo we-0.01 ~ 0.1 UF. Ukukhethwa kwesikhundla se-capacitor ngokuvamile kususelwa ekubuyiselweni kohlelo olusebenzayo F. Ngaphezu, i-capacitor eyi-101 kanye ne-0.01 uf ceramic capacitor nayo iyadingeka phakathi komugqa wamandla wesekethe.

I-11: Ingxenye yehora lokujikeleza kwehora kufanele isondele ngangokunokwenzeka kwi-Pin Signal Pin eyodwa ye-chip eyodwa microcomputer chip ukuze unciphise ubude be-Connection of the Clock Circuit. Futhi kungcono ukungasebenzisi ucingo olungezansi.
