PCB umqondo wokwenza: Ukukhiqizwa kwe-PCB kuqala nge-substrate ye-PCB eyenziwe nge-Glass Epoxy noma izinto ezifanayo. Isinyathelo sokuqala sokwenziwa ukuklama izintambo ze-PCB eku-inthanethi phakathi kwezingxenye ngokusebenzisa indlela yokudluliswa kwe-Subtractive ukuze “uphrinte” ulayini onegethivu webhodi le-PCB eliklanywe ku-conductor yensimbi.

Ubuqili ukusabalalisa ungqimba oluncane lwefoyile yethusi phezu kobuso bonke bese ususa noma ikuphi okweqile. Uma wenza i-PCB enephaneli ephindwe kabili, i-copper foil izomboza izinhlangothi zombili ze-substrate. Futhi ngifuna ukwenza ibhodi ye-multilayer ukuze ukwazi ukwenza ipuleti lobuso eliphindwe kabili elinokunamathisela okwenziwe ngocingo “cindezela ukuvala”.

Okulandelayo, ukubhoboza nokucwenga okudingekayo ukuze kuxhunywe izingxenye kungenziwa ebhodini le-PCB. Ngemuva kokubholwa ngumshini njengoba kudingeka, izimbobo kufanele zifakwe ngaphakathi (Kufakwe ubuchwepheshe obugobhoza ngembobo, i-PTH). Ngemva kokwenza ukwelashwa kwensimbi ngaphakathi komgodi, imigqa yangaphakathi yesendlalelo ngasinye ingaxhunywa komunye nomunye.

Izimbobo kumele zisuswe imfucumfucu ngaphambi kokuthi kuqale ukucwecwa. Lokhu kungenxa yokuthi i-resin epoxy izokhiqiza ushintsho oluthile lwamakhemikhali ngemuva kokushisa, futhi izomboza ungqimba lwangaphakathi lwe-PCB, ngakho-ke kufanele isuswe kuqala. Ukuhlanza nokucwenga kwenziwa ngenqubo yamakhemikhali. Okulandelayo, upende we-solder (inki ye-solder) usetshenziselwa intambo yokwakha engaphandle ye-PCB ukuze i-wiring ye-PCB ingathinti ingxenye yesingxobo.

Amalebula wezinto ezahlukahlukene abese ephrintwa ebhodini lesifunda ukukhombisa indawo yengxenye ngayinye. Akufanele imbozwe kunoma iyiphi i-wiring design ye-PCB noma umunwe wegolide, ngaphandle kwalokho kunganciphisa ukuthengiswa noma ukuzinza kokuxhumeka kwamanje. Ukwengeza, uma kukhona uxhumano lwensimbi, ingxenye “yomunwe” ivamise ukugqitshwa ngegolide ukuze kuqinisekiswe ukuxhumeka kwamanje kwekhwalithi ephezulu uma ifakwe ku-slot yokwandisa. Ekugcineni, kukhona ukuhlolwa. Ukuhlola i-PCB yesekethe emfishane noma isekethe evulekile, ukuhlolwa kwe-optical noma i-electronic kungasetshenziswa. Ukuhlolwa okubonakalayo kusetshenziswa ukuskena ukuthola ukukhubazeka ezingqimbeni, kuyilapho izivivinyo zikagesi zisebenzisa i-flyprobe ukuhlola konke ukuxhumana. Ukuhlolwa kwe-elekthronikhi kunembe kakhulu ekutholeni amasekhethi amafushane noma amakhefu, kodwa ukuhlola kwe-optical kungathola kalula izinkinga ezinezikhala ezingalungile phakathi kwamakhondakta.

I-PCB substrate kahle, ngemva kokuba ucezu oluqediwe lwebhodi eliyinhloko lusemishini ye-PCB substrate ngokusho kwesidingo sezingxenye ezinkulu nezincane – sebenzisa umshini wokubeka we-SMT othomathikhi wokuqala we-IC chip kanye nezingxenye ze-SMD “welding, ipulaki yezandla eminye imishini yenza umsebenzi, ngokusebenzisa inqubo ye-wave / reflow soldering izingxenye ze-splice ziqiniswe ngokuqinile ku-PCB, Kwenziwa i-motherboard. Indlela yokwelashwa: Isigaba sangaphansi:

I-1, ukunakekelwa kwephansi: gcina izinkuni phansi, kufanele uvikele ifilimu kapende ebusweni bayo ngaphezu kwakho konke, awukwazi ukulimaza “ukubukeka” kwayo, nokho, ngenxa yefilimu yopende yezinkuni ezihlukene, gcina indlela efanayo futhi ngayinye. akufani.

I-Nitro wood varnish floor: Sula okungekuhle ngendwangu emanzi noma amanzi, funa ulahlekelwe ukucwebezela negobolondo. Onke amanga phakathi kwengxenye yonyaka noma izinyanga ezimbalwa, xubha nge-glazing wax besmear, uphinde uthathe i-cotton gauze ehlanzekile yesula elandelayo. Sebenzisa ithawula elithambile noma intambo kakotini ngezikhathi ezijwayelekile sula uthuli ethini lefilimu likapende. Naka ukuvimbela ukuchayeka kanye nokubhema.

I-lacquer ebanzi ne-lacquer floor: akukwazi ukusula kaningi ngamanzi acacile webhulashi lokushisa okuphansi.

Hlanganani ibhodi le-ammonia fat lacquer floor floor: ukusula okungathandeki ngamanzi, hleze usule amafutha angaphezulu, futhi unciphise ukucwebezela kobuso. I-Alcohol acerbity varnish floor: Indwangu emanzi noma ithawula elithambile ingasetshenziswa uma usebenzisa i-supepe, into engathandeki yokudlula eshisayo kulolu hlobo lwephansi, ayikwazi ukumboza indawo ngephepha lepulasitiki noma into yohlobo lwephepha. Okwesibili, ukugcinwa kokhuni phansi kufanele futhi banake ukugwema metal esindayo amathuluzi abukhali, tile ingilazi, nail nezinye izinto ezinzima ukunwaya phansi, musa ukuhambisa ifenisha in the floor surface donsa move; Gwema ukukhipha izinkinobho zikagwayi phansi bese ubeka izinto ze-asidi nezama-alikhali; Ungabeki ngqo igedlela, isitofu nezinye izinto ezishisa kakhulu.

Izinkuni phansi ngemuva kokusebenzisa isikhathi eside, kuvela into endala, kufanele kukhuphuke ngesikhathi se-lacquer. Indlela ye-Lacquer inezinhlobo ezimbili: uhlobo olulodwa ukukhuphuka ngokuqondile kwe-lacquer kanye nemibala, indlela yayo kanye nefenisha yokubaza kuyafana, i-wax yaphansi ku-besmear ngemva kokulinda okomile, 2 iwukuba awudingi noma yimuphi umbala ukwenza umbala wesisekelo, futhi udinga hhayi noma yimuphi upende, shayela nge-wax yaphansi ngqo kepha. Ngoba iphansi lezinkuni luhlobo lwezinto zemvelo, gqoka kahle hhayi nje kuphela, futhi lisahlehla njengesikhathi usuku ngalunye oludlulayo luphelele, luyimvelo ngokwengeziwe, ikakhulukazi ibhulashi elihlanzekile lomuthi wokhuni phansi, luyoba olukhanyayo, olubushelelezi, oluhle kakhulu.

2, ukugcinwa kwesitezi se-laminate

Ukusetshenziswa kwe-aggrandizement wood floor kugcina kulula, bafuna ukuqaphela amaphuzu alandelayo kuphela ekusetshenzisweni kwansuku zonke, kungaqinisekisa ukusetshenziswa okujwayelekile kwephansi.

(1) Zonke izitezi zokhuni zizoshintsha umswakama wazo ngokwanda nokuncipha komswakama noma ukushintsha kwezinga lokushisa, okuthinta ukunwetshwa kwephansi. Isizathu kufanele sifane nokuvikela isikhumba esifanayo, sigcine umswakama ofanele phansi.

(2) Iphansi ngokuvamile ayidingi ukufakwa kwe-wax nokudweba. Ungasebenzisi i-sandpaper ukupholisha.

(3) Kunconywa ukubeka i-MATS yokuhlikihla emnyango ukuvimbela izinhlayiya zothuli ukuthi zingangeni futhi zilimaze phansi.

(4) Amabala namabala kawoyela phansi kufanele ahlanzwe ngabahlanza indlu. Ungasebenzisi amanzi amaningi ukuhlanza phansi.

(5) izindawo ezisenyakatho ezomile, ebusika kufanele zinake ukwanda komswakama ongaphansi, nge-mop mop emanzi, ngokufanele ukwandisa umswakama ongaphezulu, ingaxazulula ngempumelelo igebe phansi nokuqhekeka. Uma imifantu ivela ezindaweni ezihlukile, sicela wazise iyunithi yokuthengisa ngesikhathi bese ugcwalisa izingxenye. Ngemuva kokugcwalisa, khulisa umswakama ongaphezulu ukuze usize ukutakula phansi.

Ngesikhathi semvula, sicela uvale ngokucophelela iWindows ukuze ingani.

(7) Sicela unake ukunakekelwa kokushisa, umoya opholile nezinye izinto zasendlini ukugwema ukuvuza kwamanzi phansi okumanzi. Uma kwenzeka kutholakala amanzi e-bubble floor, kufanele adabule indawo emanziswe amanzi ngokushesha okukhulu, endaweni yomthunzi umoya womile noma wokuthengisa wesaziso ngesikhathi esifanele wenza ukucubungula.

(8) Emnyango wethoyilethi nasekhishini, kufanele kubhekwe ukuhlanzwa kwamanzi ngesikhathi esifanele.

(9) Ungahuduli lapho uphatha ifenisha. Kungakuhle ukuyiphakamisa.
