Zininzi iindidi ze-PCB ngokusebenzisa izihlwithi zemingxunya, kunye nezithintelo ezahlukeneyo zinokukhethwa ngokweemfuno ezahlukeneyo zesicelo kunye neemfuno zoyilo. Oku kulandelayo kuya kunika i-Aperture ye-PCB ye-PCB eqhelekileyo ngokusebenzisa imingxunya kwaye umahluko phakathi kwe-PCB ngemingxunya nangeemingxunya.
一, uhlobo lwe-aperture ye-PCB ngomngxunya
1. I-Aperture esemgangathweni (i-PCB esemgangathweni) Olu gadalala luhlala lusetyenziswa ukukhusela ibhodi ye-PCB kunye nonxibelelwano lwePun.

I-2. I-Aperture ye-Micro Colere: I-Aperture ye-Micro Hole ibhekisa kwimngxunya ejikelezayo enobubanzi obungaphantsi kwe-0.4mm. Ngokwandisa ubuninzi bezixhobo ze-elektroniki, kukho imfuno ephezulu yoyilo lwePCB, ke izithinteli ze-microre ngokuthe ngcembe ngokuthe ngcembe. Izicelo ze-microaperture zibandakanya izixhobo ezincinci ze-elektroniki ezifana ne-LAPTOPS kunye neefowuni eziphathwayo.

I-3. Umngxunya odityanisiweyo (umngxunya we-tread): Imingxunya enentambo inikiwe ngemingxunya, ihlala isetyenziselwa ukufaka izinto ezinemigca enesitayile, njengamachiza okanye inkcitho.

二, umahluko phakathi kwe-PCB ngomngxunya nangomngxunya

I-PCB ngomngxunya kwaye ngomngxunya zahlukile ekusetyenzisweni kweBhodi yePCB, ubukhulu becala lolahluko ulandelayo:

I-1. I-PCB yokuyila Injongo ye-PCB: Imingxunya ye-PCB ziingcango ezigciniweyo ngoyilo, kwaye iya kuqwalaselwa ukuba iqhagamshele ubuncinci bee-PCB ezimbini. Ngemingxunya yenzelwe ukudibanisa umaleko othile okanye icandelo, kwaye indawo yazo igqitywe ziimfuno zoyilo.

2, uqhagamshelo lwesiginali (uqhagamshelo lwesiginali): I-PCB ngomngxunya yipini yomqondiso kwi-famier ukuya kwenye indawo yokufezekisa ukuhanjiswa kwesiginali. Ngemingxunya ikakhulu isetyenziselwa ukulungisa iibhodi zePCB kunye nezinto kwaye zinike inkxaso yoomatshini.

I-3. Inkqubo yokutyumba: Imingxunya yokutsalwa: I-PCB imingxunya iya kuphathwa ngezixhobo ezizodwa kunye nezixhobo ngexesha lenkqubo yokwenziwa, idla ngokufaka i-elektroniki yokwandisa ukuqhubela phambili kombane. Imngxunya ilula, ihlala ifuneka kuphela ukuba idityaniswe nomngxunya kwindawo ehambelana nayo.

4. Inkxaso yesakhiwo: ubukho bemingxunya ye-PCB buyonyusa uzinzo kunye nobungqola beBhodi yePCB, kwaye badlala indima yokuxhasa. Nangona i-Hole ingakonyusa inqanaba elithile lokuqina, eyona njongo iphambili kukubonelela ngemisebenzi emiselweyo nexhunyiweyo.

Kwisishwankathelo, i-aperture ye-PCB ngomngxunya ibandakanya i-aperture esemgangathweni, imicroaperture kunye nomngxunya ontambo. Umahluko phakathi kwe-PCB ngokusebenzisa imingxunya kwaye ngemingxunya ibonakaliswa ikakhulu kwinjongo yoyilo, uqhagamshelo lwesiginali, itekhnoloji yetekhnoloji kunye nenkxaso yolwakhiwo. Uyilo olwahlukileyo lwe-PCB kunye neemfuno zendibano zinokufezekiswa ngokukhetha iintlobo ezahlukeneyo ze-adrerture kwaye zisebenzisa ilungele imingxunya okanye kwimingxunya.
