Ngenxa yezizathu eziningi, kunezinhlobo eziningi ezahlukene zamaphrojekthi wokukhiqiza we-PCB adinga izinsimbi ezithile zethusi. Sithola imibuzo evela kumakhasimende angawazi umqondo wesisindo sethusi ngezikhathi ezithile, ngakho lesi sihloko sihlose ukuxazulula lezi zinkinga. Ngaphezu kwalokho, lokhu okulandelayo kuhlanganisa ulwazi mayelana nomthelela wezisindo zethusi ezahlukene kwinqubo yokuhlanganisa i-PCB, futhi sithemba ukuthi lolu lwazi luzoba usizo ngisho nakumakhasimende asevele ejwayele umqondo. Ukuqonda okujulile kwenqubo yethu kungakusiza ukuthi uhlele kangcono ishejuli yokukhiqiza kanye nezindleko zizonke.

Ungacabanga ngesisindo sethusi njengobukhulu noma ukuphakama komkhondo wethusi, okuyisilinganiso sesithathu ukuthi idatha yongqimba yethusi yefayela leGerber ayicabangi. Iyunithi yokulinganisa ingama-ounces ngonyawo lwesikwele (oz / ft2), lapho u-1.0 oz wethusi eguqulwa abe ukujiya okungu-140 mils (35 μm).

Ama-PCB ethusi elisindayo ngokuvamile asetshenziswa ezintweni zikagesi zikagesi noma kunoma iyiphi into engase ihlupheke ngenxa yezindawo ezinokhahlo. Ukulandela ngomkhondo okukhudlwana kunganikeza ukuqina okukhulu, futhi kungavumela umkhondo ukuthi uthwale okwamanje ngaphandle kokukhulisa ubude noma ububanzi bokulandelela kuye kuleveli engenangqondo. Ngakolunye uhlangothi lwesibalo, izisindo zethusi ezilula ngezinye izikhathi zicaciswa ukuze kuzuzwe ukuvinjelwa komkhondo othile ngaphandle kwesidingo sobude bokulandela umkhondo obuncane kakhulu noma ububanzi. Ngakho-ke, lapho ubala ububanzi bokulandelela, "isisindo sethusi" siyinkambu edingekayo.

Ivelu yesisindo sethusi esetshenziswa kakhulu yi-ounce engu-1.0. Qedela, ilungele amaphrojekthi amaningi. Kulesi sihloko, kubhekiselwa ekubambiseni isisindo sethusi sokuqala enanini eliphezulu ngesikhathi senqubo yokukhiqiza ye-PCB. Uma ucacisa ikhotheshini yesisindo sethusi edingekayo eqenjini lethu labadayisi, sicela ubonise inani lokugcina (elipuletiwe) lesisindo sethusi esidingekayo.

Ama-PCB ethusi awugqinsi athathwa njengama-PCB anogqinsi lwethusi lwangaphandle nangaphakathi olusukela ku-3 oz/ft2 ukuya ku-10 oz/ft2. Isisindo sethusi se-PCB yethusi esindayo esikhiqizwe sisuka kuma-ounces angu-4 ngonyawo lwesikwele kuya kuma-ounces angu-20 ngonyawo lwesikwele ngasinye. Isisindo sethusi esithuthukisiwe, esihlanganiswe nongqimba oluqinile lokucwenga kanye ne-substrate efanelekile emgodini odlulayo, kungashintsha ibhodi lesifunda elibuthaka libe inkundla yezintambo eziqinile nethembekile. Ama-conductor ethusi esindayo azokwandisa kakhulu ukushuba kwayo yonke i-PCB. Ubukhulu bethusi kufanele bucatshangelwe ngaso sonke isikhathi ngesikhathi sesiteji sokuklama isifunda. Umthamo wamanje wokuthwala unqunywa ububanzi nogqinsi lwethusi esindayo.

Inani eliphakeme lesisindo sethusi ngeke likhulise ithusi ngokwalo kuphela, kodwa futhi libangele isisindo esengeziwe sokuthumela kanye nesikhathi esidingekayo emsebenzini, ubunjiniyela bezinqubo, nokuqinisekiswa kwekhwalithi, okuholela ekukhuphukeni kwezindleko kanye nokwanda kwesikhathi sokulethwa. Okokuqala, lezi zinyathelo ezengeziwe kufanele zithathwe, ngoba ukugqoka kwethusi okwengeziwe ku-laminate kudinga isikhathi esiningi sokuqopha futhi kufanele kuhambisane neziqondiso ezithile ze-DFM. Isisindo sethusi sebhodi lesifunda siphinde sithinte ukusebenza kwayo okushisayo, okubangela ukuthi ibhodi lesifunda libambe ukushisa ngokushesha ngesikhathi sesiteji se-reflow soldering somhlangano we-PCB.

Nakuba ingekho incazelo evamile yethusi esindayo, ngokuvamile kuyamukelwa ukuthi uma ama-ounces (oz) angu-3 (oz) noma ngaphezulu ethusi esetshenziswa ezandlaleni zangaphakathi nezangaphandle zebhodi lesifunda eliphrintiwe, libizwa ngokuthi i-PCB yethusi esindayo. Noma iyiphi isekethe enogqinsi lwethusi oludlula ama-ounces angu-4 ngonyawo lwesikwele ngasinye (ft2) nayo ihlukaniswa njenge-PCB yethusi esindayo. Ithusi eledlulele lisho ama-ounces angama-20 kuye kwangama-200 ngonyawo lwesikwele ngasinye.

Inzuzo eyinhloko yamabhodi wesifunda sethusi esindayo yikhono labo lokumelana nokuchayeka kaningi emifuleni eyeqile, izinga lokushisa eliphezulu kanye nemijikelezo yokushisa ephindaphindiwe, engabhubhisa amabhodi wesifunda avamile phakathi nemizuzwana embalwa. Ipuleti yethusi esindayo inomthamo ophezulu wokuthwala, okwenza ihambisane nezinhlelo zokusebenza ngaphansi kwezimo ezinzima, ezifana nemikhiqizo yemboni yezokuvikela kanye ne-aerospace. Ezinye izinzuzo zamabhodi wesekethe yethusi esindayo zifaka:

Ngenxa yezisindo zethusi eziningi ezisesilinganisweni esifanayo, usayizi womkhiqizo uhlangene
Ikhopha esindayo egqitshwe ngezimbobo idlula amandla amanje aphakeme nge-PCB futhi isize ukudlulisa ukushisa kusinki yokushisa yangaphandle.
I-airborne high power density planar transformer

Amabhodi wesekethe esindayo aphrintiwe angasetshenziswa ngezinhloso eziningi, njengama-planar transformer, ukuchithwa kokushisa, ukusatshalaliswa kwamandla aphezulu, iziguquli zamandla, njll. Isidingo samabhodi ethusi esindayo ahlanganiswe kumakhompiyutha, izimoto, ezempi, nokulawulwa kwezimboni siyaqhubeka nokukhula. Amabhodi esekethe aphrintiwe ethusi elisindayo nawo asetshenziselwa:

Ukunikezwa kwamandla kagesi
Ukuthunyelwa kukagesi
Imishini yokushisela
Imboni yezimoto
Abakhiqizi bephaneli yelanga, njll.

Ngokwezidingo zokuklama, izindleko zokukhiqiza ze-PCB yethusi esindayo ziphakeme kunalezo ze-PCB ezejwayelekile. Ngakho-ke, lapho umklamo uyinkimbinkimbi kakhulu, izindleko zokukhiqiza ama-PCB ethusi esindayo ziyakhuphuka.
