1. IPlum Blossom Pad.

1: Imbobo yokulungisa idinga ukungahlangani. Ngesikhathi sokuthengisa amagagasi, uma umgodi wokulungiswa ungumgodi we-metalized, i-tin izovimba umgodi ngesikhathi sokubonisa.

2 Ngemuva kokuthi izimbobo ze-quincanx zifakwe nge-PCB Shell Contents, eqinisweni, i-GND ixhumeke emhlabeni. Ngezikhathi ezithile, igobolondo le-PCB lidlala indima evikayo. Vele, abanye abadingi ukuxhuma imbobo ekhuphukayo kwinethiwekhi ye-GND.

3 I-Plum Blossom Hole, noma ngabe ukucindezela kuguquka kanjani, kungahlala kugcina isikulufa sigxile.

2. Cross flower pad.

Amaphampu wezimbali we-Cross abizwa nangokuthi ama-thermal pads, amaphilisi asolwandle ashisayo, njll. Umsebenzi wawo ukunciphisa ukuncipha kokushisa kwepayipi ngesikhathi sokuthengisa, ukuze uvikele ukuthengisa okubonakalayo noma ukugcwala kwe-PCB okubangelwa ukudicilela phansi ngokweqile.

1 Lapho pad yakho ingumhlabathi. Iphethini yesiphambano inganciphisa indawo yocingo lomhlabathi, yehlisa ijubane ijubane lokuhlanza ukushisa, bese lisiza ukufudumala.

2 Lapho i-PCB yakho idinga ukubekwa komshini kanye nomshini wokuthengisa womshini, i-Cross-Pattern Pad ingavimba i-PCB ukuthi ibheke phezulu (ngoba ukushisa okuningi kuyadingeka ukuncibilikisa ukunamathisela solder)

3. I-Teardrop Pad

Ama-teardrops axhumanisa ngokweqile phakathi kwepadi nocingo noma ngocingo kanye ne-via. Inhloso ye-teardrop ukugwema iphuzu lokuxhumana phakathi kocingo kanye ne-pad noma nge-wire kanye ne-via lapho ibhodi yesekethe lishaywa ngamandla amakhulu angaphandle. Nqamula, ngaphezu kwalokho, ukusetha ama-teardrops nakho kungenza ibhodi yesekethe ye-PCB ibukeke ibe yinhle ngokwengeziwe.

Umsebenzi we-Teardrop ukugwema ukwehla okungazelelwe komugqa wesiginali futhi ubangele ukuboniswa, okungenza ukuxhumana phakathi komlandeli kanye ne-pad yengxenye kube yinguquko ebushelelezi, futhi uxazulule inkinga ukuthi ukuxhumana okuphakathi kwepanini nokulandela umkhondo kuphulwe kalula.

1. Lapho u-soldering, ungavikela i-pad futhi ugweme ukuwa kwepayipi ngenxa yokuthengisa okuningi.

2. Qinisa ukuthembeka kokuxhumeka (ukukhiqizwa kungakugwema ukugcwala okungalingani, imifantu ebangelwa ukuphambuka, njll.)

I-3. Ukuvikelwa okubushelelezi, ukunciphisa ukugxuma okubukhali kokungaphandle

Ekwakhiweni kweBhodi Yesekethe, ukuze wenze i-pad stror futhi uvikele i-pad kanye nocingo ukuthi lunqanyulwe ngesikhathi sokukhiqiza iBhodi, kuvame ukusetshenziselwa ukuguqula indawo, ngakho-ke kuvame ukubizwa ngokuthi yi-teardrop (i-teardrops)

4. Igiya lokukhipha

Uke wabona amanye amandla okushintsha abanye abantu agcinwe ngamabomu i-foil ye-sawtooth anale ithusi ngaphansi kwemodi ejwayelekile? Uyini umphumela othize?

Lokhu kubizwa ngokuthi izinyo lokukhipha, sula igebe noma i-Spark Gap.

Igebe le-Spark liyi-triangles enonxantathu ngama-angles abukhali akhomba omunye komunye. Ibanga eliphakeme phakathi komunwe liyi-10mil kanti ubuncane bungu-6mil. I-Delta eyodwa isekelwe, kanti enye ixhumeke kulayini wesiginali. Lo Thinalle akuyona ingxenye, kepha yenziwa ngokusebenzisa izingqimba ze-foil zethusi kwinqubo yokuhamba ngomzila we-PCB. Lawa ma-Triangles adinga ukusethwa phezu kwesendlalelo esiphezulu se-PCB (ICompnentwentside) futhi ayikwazi ukumbozwa imaskhi yomthengisi.

Ekushintsheni kokushintsha kwamandla kwamandla e-Power Supply Surven noma ukuhlolwa kwe-ESD, kuzokwenziwa ugesi ophakeme emikhawulweni yomibili yemodi ejwayelekile nokuphonsa kuzokwenzeka. Uma isondele kumadivayisi aseduze, amadivaysi azungezile angalimala. Ngakho-ke, ishubhu lokukhipha noma i-varistor lingaxhunywa ngokufana ukuze lilinganise amandla ayo, ngaleyo ndlela lidlale indima yokucima i-ARC.

Umphumela wokubeka amadivaysi okuvikela umbani muhle kakhulu, kepha izindleko ziphakeme kakhulu. Enye indlela ukungeza amazinyo okukhipha kuzo zombili izinhlangothi ze-Inductor ejwayelekile ngesikhathi se-PCB Design, ukuze i-inductor ikhiphe ngezeluleko ezimbili zokukhipha, ukuze ikhiphe ezinye izindlela, ukuze ithonya elizungezile nethonya lesigaba sakamuva lincishisiwe.

Igebe lokukhipha alidingi izindleko ezingezekile. Ingadonswa lapho idweba ibhodi le-PCB, kepha kubalulekile ukuqaphela ukuthi lolu hlobo lwegebe lokukhipha luhlobo lwe-Air-Type Conf Uma kusetshenziswa ngezikhathi lapho kwenzeka khona, lapho imali yekhabhoni izokhiqizwa khona ngamaphoyinti amabili anxantathu phakathi kokukhishwa okuningana ngenxa yokukhishwa okufushane, okuzokwenza umjikelezo omfushane ngenxa yegebe lokukhipha futhi adale umjikelezo oyisikhashana womugqa wesiginali phansi. Okuholela ekuhlulekeni kwesistimu.
