Abstract: In Isantya esiphezulu sePCB uyilo, ngoyilo lomngxunya yinto ebalulekileyo, yenziwe ngomngxunya, iphedi ejikeleze umngxunya kunye NAMANDLA indawo yokuzihlukanisa, ihlala yahlulwe yangumngxunya ongaboniyo, umngxunya ongcwatyelweyo nangomngxunya iintlobo ezintathu. Ngokusebenzisa uhlalutyo capacitance parasitic kunye inductance sisidleleli kuyilo PCB, amanye amanqaku ingqalelo ingqalelo kuyilo ngesantya esiphezulu PCB ziyashwankathelwa.

Amagama aphambili: ngokusebenzisa umngxuma; Ukusebenza kweParasitic; Ukunyanzeliswa kweParasitic; Itekhnoloji yomngxunya engangeniyo

Uyilo olukhawulezayo lwePCB kunxibelelwano, ikhompyuter, usetyenziso lwemifanekiso, zonke izinto zobugcisa ezixabisekileyo-ezongeziweyo kuyilo lwemveliso ye-elektroniki ekusetyenzisweni kwamandla asezantsi, imitha ye-electromagnetic ephantsi, ukuthembeka okuphezulu, i-miniaturization, ukukhanya-umsebenzi njl. ukufezekisa ezi njongo, kuyilo olukhawulezayo lwePCB, kuyilo lomngxunya yinto ebalulekileyo.

Ngokusebenzisa umngxuma yinto ebalulekileyo kuyilo multi-maleko PCB, umngxuma ngokusebenzisa ubukhulu becala yenziwe ngamalungu amathathu, omnye umngxuma; Eyesibini yindawo yephedi ejikeleze umngxuma; Okwesithathu, indawo eyedwa yokwahlulahlula KWAMANDLA. Inkqubo yomngxunya kukubeka umaleko wentsimbi kumphezulu wesilinda wodonga lomngxunya ngokusebenzisa ukufakwa kwemichiza ukudibanisa ifoyile yobhedu ekufuneka idityaniswe kumaleko ophakathi. Amacala aphezulu kunye asezantsi emngxunyeni enziwe kwimo yesiqhelo yephedi, enokunxibelelana ngokuthe ngqo namacala aphezulu nangaphantsi emgceni, okanye angaxhunyiwe. Ngemingxunya inokusetyenziselwa unxibelelwano lombane, ukulungiswa okanye ukubeka izixhobo.

Isantya esiphezulu sePCB ngokuyila komngxuma

Ngokusebenzisa imingxunya yahlulwe yangamacandelo amathathu: umngxuma ongaboniyo, umngxunya ongcwatyelweyo nangomngxunya lowo.

Umngxuma oyimfama: umngxunya ubekwe kumphezulu kunye nasezantsi kwibhodi yesekethe eprintiweyo enobunzulu obuthile bokuqhagamshela isekethe yomphezulu kwisekethe yangaphakathi engezantsi. Ubunzulu bomngxuma ngokuqhelekileyo abugqithi kumyinge othile womngxuma.

Umngxunya ongcwatyelweyo: umngxunya wokudibanisa umaleko wangaphakathi webhodi yesekethe eprintiweyo engafikeleli kumphezulu webhodi yesekethe eprintiweyo.

Umngxuma oyimfama kunye nomngxunya ongcwatyelweyo zimbini iintlobo zemingxunya zibekwe kumaleko angaphakathi webhodi yesekethe, i-laminating isebenzisa inkqubo yokubumba umngxuma ukugqibezela, kwinkqubo yokwakheka nayo inokuthi igqale iileya ezininzi zangaphakathi.

Ukungena-kwimingxunya ebaleka yonke ibhodi yesekethe kwaye inokusetyenziselwa unxibelelwano lwangaphakathi okanye njengokufaka kunye nokubeka imingxunya yezinto. Ngenxa yokuba umngxuma kwinkqubo kulula ukufezekisa, iindleko ziphantsi, ke kusetyenziswa ibhodi yesekethe eprintiweyo ngokubanzi.
