Ukwenziwa Kwe-PCB Eguquguqukayo: Isakhiwo, Isakhiwo, Nezinhlobo Zesitaki

Yethula:

Ukwenziwa kwe-PCB eguqukayo kudlala indima ebalulekile embonini yokukhiqiza izinto zikagesi.Njengoba ubuchwepheshe buthuthuka, isidingo sama-PCB avumelana nezimo sikhule kakhulu.Kulo mhlahlandlela oyinhloko, sizohlola ukwakhiwa kwe-PCB eguquguqukayo, isakhiwo, nezinhlobo zezitaki.Kubalulekile ukuqonda amagama angukhiye alandelayo:Ukwenziwa Kwe-PCB Eguquguqukayo, Isakhiwo se-PCB Esishintshashintshayo, Ukuqina Kwethusi Kwe-PCB Evumelana Nezimo, I-Flexible PCB Solder Mask, I-Flexible PCB Layout, Flexible PCB Adhesive Sheet, kanye ne-Flexible PCB Layup Izinhlobo njengoba zibalulekile ekwenzeni umkhiqizo wakho uphumelele.Kubalulekile.

1. Ulwazi oluyisisekelo lokukhiqiza i-PCB eguquguqukayo:

A. Incazelo nezici zebhodi eliguquguqukayo: I-PCB eguquguqukayo, eyaziwa nangokuthi isekethe eguquguqukayo, ibhodi lesifunda eliphrintiwe elingagotshwa, ligoqwe, noma lisontwe ngaphandle kokuphuka.Banikeza izinzuzo ezimbalwa phezu kwama-PCB aqinile, okuhlanganisa ukuguquguquka, ukulula, nokuqina.Lezi zakhiwo zizenza zilungele izinhlelo zokusebenza ezihlukahlukene, ikakhulukazi lezo ezidinga ama-electronics ahlangene futhi agobekayo.

B. Isakhiwo se-PCB esivumelana nezimo: Inqubo yokwakha ye-PCB eguquguqukayo ihilela ukusetshenziswa kwama-substrates aguquguqukayo.Ama-substrates asetshenziswa kakhulu yi-polyimide ne-polyester, ehlinzeka ngokuguquguquka okudingekayo kanye nezakhiwo zokuvikela ezidingekayo kuma-PCB aguquguqukayo.Lawa ma-substrates athola uchungechunge lwezinyathelo zokukhiqiza ezifana ne-etching, plating, kanye ne-lamination ukudala iphethini yesekethe efunekayo.

C. Qonda ukujiya kwethusi ku-PCB eguquguqukayo: Ugqinsi lwethusi ludlala indima ebalulekile ekusebenzeni kwe-PCB eguquguqukayo.Inquma umthamo wamanje wokuthwala, i-impedance, kanye nokuvumelana nezimo kwe-PCB.Ukukhetha okuhlukile kokuqina kwethusi kungenziwa ngokuya ngezidingo ezithile zomklamo.Ithusi eliwugqinsi linikeza amandla aphezulu okuthwala wamanje kodwa futhi yehlisa ukuguquguquka kwe-PCB.Kufanele kwenziwe ibhalansi efanele phakathi kwalezi zici ukuze kuzuzwe ukusebenza kahle.

2. Izingxenye ezibalulekile zokukhiqiza i-PCB eguquguqukayo:

A. Imaski ye-solder ye-PCB eguquguqukayo: Imaski ye-solder iyisendlalelo esivikelayo esimboza imikhondo yethusi engenalutho ku-PCB.Isiza ukuvimbela amabhuloho e-solder, ukugqwala, nezikhindi zikagesi ngesikhathi sokushisela.I-PCB eguquguqukayo isebenzisa izinto ezikhethekile zemaski ye-solder ukuqinisekisa ukuguquguquka nokuqina.Ukukhethwa kwemaski ye-solder ye-PCB eguquguqukayo kanye nenqubo yokufaka isicelo kudinga ukucatshangelwa ngokucophelela komklamo we-PCB kanye nokusetshenziswa kwayo okuhlosiwe.

B. Isakhiwo se-PCB Esiguquguqukayo: Isakhiwo se-PCB esiklanywe kahle, esivumelana nezimo sibalulekile ekusebenzeni okuhle nokuthembeka.Kubandakanya ukubekwa kwezingxenye, umzila wokulandela umkhondo, nokucatshangelwa kobuqotho besignali.Izingxenye kumele zibekwe ngendlela evumela i-PCB ukuthi igobe futhi igobe ngokufanele.Imikhondo kufanele ihanjiswe ukuze kuncishiswe ingcindezi ezindaweni eziguqukayo futhi kuqinisekiswe ukudluliswa kwesignali okusebenzayo.Imikhuba engcono kakhulu yokuklama isakhiwo se-PCB esivumelana nezimo ihlanganisa ukusebenzisa imikhondo egobile, ukugwema ama-engeli abukhali, nokuqinisekisa imvume eyanele phakathi kokulandela umkhondo.

C. Ishidi lokunamathela le-PCB elivumelana nezimo: Ishidi elinamathelayo lisetshenziswa ekwenzeni i-PCB eguquguqukayo ukuze kuhlanganiswe izendlalelo ezahlukene.Inikeza amandla emishini, ukuzinza, kanye nokwahlukanisa.Kunezinhlobo ezahlukene zamashidi okunamathela atholakalayo, njengamashidi asekelwe ku-acrylic, amashidi asekelwe epoxy, namashidi asekelwe enjoloba.Ukukhethwa kweshidi lokunamathela kuncike ezintweni ezifana nokumelana nezinga lokushisa, izidingo zokuvumelana nezimo, nokuhambisana nezinye izinto.Ukukhetha ishidi lokunamathela elifanele kubaluleke kakhulu ukuze uqinisekise ukwethembeka nokuqina kwe-PCB yakho eguquguqukayo.

3. Izinhlobo zezitaki ze-PCB eziguquguqukayo:

A. Isethulo sesitaki se-PCB: Isitaki se-PCB sisho ukuhlelwa kwezendlalelo ezihlukene ku-PCB.Ekwenziweni kwe-PCB evumelana nezimo, ukunqwabelanisa kudlala indima ebalulekile ekuthembekeni kwesignali, ekulawuleni i-impedance, kanye nokuphatha okushisayo.Ngokukhetha ngokucophelela nokuhlela izendlalelo, abaklami bangathuthukisa ukusebenza kwama-PCB aguquguqukayo.

B. Izinhlobo Zokuhlela Ezivamile Ze-PCB Ezivumelana Nezimo: Kunezinhlobonhlobo zezinhlobo zokubeka ezisetshenziswa ekukhiqizeni i-PCB eguquguqukayo, okuhlanganisa ungqimba olulodwa, ungqimba olukabili, kanye nokucushwa kwezendlalelo eziningi.Uhlobo ngalunye lokupakisha lunezinzuzo zalo kanye nemikhawulo.Ama-PCB ongqimba olulodwa aguquguqukayo ayinketho elula futhi engabizi kakhulu, kodwa anamandla omzila alinganiselwe.I-PCB enezingqimba ezimbili eguquguqukayo inikeza izinketho eziningi zezintambo futhi ingamukela imiklamo eyinkimbinkimbi.Ama-PCB anwebekayo amaningi ahlinzeka ngokuguquguquka okukhulu komzila, nokulawula okuthuthukisiwe kwe-impedance, futhi angasekela ukuminyana kwesekethe okuphezulu.Nokho, ziyinkimbinkimbi futhi kubiza ukuwenza.

Ngokufigqiwe:

Kulo mhlahlandlela obanzi, sihlanganisa zonke izici zokwenziwa kwe-PCB eziguquguqukayo, okuhlanganisa ukwakhiwa, isakhiwo, imaski ye-solder, amashidi okunamathela, nezinhlobo zezitaki.Ukuqonda lezi zakhi ezibalulekile kuzovumela abaklami ukuthi bathuthukise ukusebenza nokuthembeka kwemiklamo yabo ye-PCB eguquguqukayo.Izinqubo nobuchwepheshe bubalulekile ekukhiqizweni kwama-PCB aguquguqukayo, futhi ngokulandela izindlela ezingcono kakhulu, abakhiqizi bangaqinisekisa ukulethwa kwemikhiqizo esezingeni eliphezulu, ethembekile ukuze kuhlangatshezwane nezidingo zemboni yezogesi.
