Ngokuphathelene nesimiso sokugcinwa kwamabhodi wesifunda se-PCB, umshini wokunamathisela othomathikhi unikeza lula ukuthengiswa kwamabhodi wesifunda we-PCB, kodwa izinkinga zivame ukuvela ekukhiqizeni amabhodi wesifunda we-PCB, okuzothinta ikhwalithi ye-solder.Ukuze kuthuthukiswe umphumela wokuhlola, okunye ukucutshungulwa kobuchwepheshe kufanele kwenziwe ebhodini elilungisiwe ngaphambi kokuhlolwa kokusebenza okuku-inthanethi kwebhodi lesifunda le-PCB ukuze kuncishiswe umthelela weziphazamiso ezihlukahlukene kwinqubo yokuhlola.Izinyathelo eziqondile zimi kanje:
.Ukulungiselela ngaphambi kokuhlolwa
Yenza isikhashana i-crystal oscillator (naka i-crystal oscillator enamaphini amane ukuze uthole ukuthi yimaphi amaphini amabili angamaphini okukhipha isignali futhi angafinyeza lawa maphini amabili. Khumbula ukuthi ezinye izikhonkwane ezimbili ziyizikhonkwane zamandla ngaphansi kwezimo ezijwayelekile futhi akumele ibe yi-short-circuited!!) Kumthamo omkhulu we-electrolytic I-capacitor kufanele futhi ithengiswe phansi ukuze ivuleke.Ngoba ukushajwa nokukhishwa kwama-capacitor amakhulu nakho kuzodala ukuphazamiseka.
2. Sebenzisa indlela yokukhishwa ukuze uhlole ibhodi lesekhethi ye-PCB yocingo
Ngesikhathi sokuhlolwa kwe-inthanethi noma ukuhlolwa kokuqhathanisa kwedivayisi, sicela uqinisekise umphumela wokuhlola ngokuqondile futhi urekhode idivayisi ephumelele ukuhlolwa (noma evamile uma kuqhathaniswa).Uma ukuhlolwa kwehluleka (noma kungabekezelelani), kungahlolwa futhi.Uma isahluleka, ungaphinda uqinisekise imiphumela yokuhlolwa kuqala.Lokhu kuyaqhubeka kuze kube yilapho idivayisi esebhodini isihloliwe (noma iqhathaniswa).Bese ubhekana nalawo madivayisi ahluleka ukuhlolwa (noma aphelelwe ukubekezelelana).
Amanye amathuluzi okuhlola aphinde anikeze ngendlela engahlelekile kodwa esebenzayo yokucubungula yamadivayisi angakwazi ukuphumelela ukuhlolwa okuku-inthanethi komsebenzi: ngoba ukunikezwa kwamandla kwethuluzi lokuhlola ebhodini lesekethe nakho kungasetshenziswa ekunikezeni amandla okuhambisanayo namandla ahambisanayo. ukunikezwa kwedivayisi ngesiqeshana sokuhlola.Uma iphinikhodi yamandla yedivayisi inqunywa kuphini eliphansi, idivayisi izonqanyulwa ohlelweni lokunikezwa kwamandla lwebhodi lesifunda.
Ngalesi sikhathi, yenza ukuhlolwa kokusebenza okuku-inthanethi kudivayisi;njengoba amanye amadivayisi ku-PCB angeke anikezwe amandla okusebenza ukuze asuse umthelela wokuphazamiseka, umphumela wangempela wokuhlola ngalesi sikhathi uzolingana “nokuhlola okungaxhunyiwe ku-inthanethi”.Izinga lokunemba lizoba phezulu kakhulu.Intuthuko enkulu.
