Ephrintiwe wesifunda ibhodi (PCB) ziyinto ebalulekile cishe kuyo yonke imboni ye-elekthronikhi. Ezinsukwini zokuqala, ukukhiqizwa kwe-PCB kwakuyindlela ehamba kancane, ejwayelekile. Njengoba ubuchwepheshe buthuthukile, inqubo iye yashesha, yakha futhi yakha ubunzima kakhulu. Ikhasimende ngalinye lidinga izinguquko ezithile kwi-PCB ngaphakathi kwemikhawulo ethile yesikhathi. Kwezinye izimo, ukukhiqizwa kwe-PCB yangokwezifiso kuthatha ihora. Kodwa-ke, uma i-PCB yangokwezifiso ivivinywa ekugcineni kwenqubo futhi ukuhlolwa kwehluleka, umenzi nekhasimende kungenzeka bangakwazi ukukhokhela ukulahleka. Yilapho i-PCB prototyping ingena khona. I-PCB prototyping yisinyathelo esiyisisekelo ekukhiqizeni i-PCB, kodwa kungani kubaluleke kangaka? Lo mbhalo ukhuluma ngqo ngokuthi yiziphi izindlela okufanele zinikezwe ama-prototypes nokuthi kungani zibalulekile.

PCB sibonelo Isingeniso

I-PCB prototyping inqubo yokuphindaphinda lapho abaklami be-PCB nonjiniyela bezama amasu amaningi wokuklama ne-PCB. Inhloso yalokhu kuphindaphindwa ukucacisa ukwakheka okuhle kakhulu kwe-PCB. Ekukhiqizeni kwe-PCB, izinto zebhodi lesifunda, izinto ezisezingeni eliphansi, izingxenye, ukwakheka kokufakwa kwezinto, izifanekiso, izingqimba nezinye izinto kubhekwa kaningi ngonjiniyela. Ngokuxuba nokufanisa ukwakheka nokukhiqizwa kwezici zalezi zinto, izindlela ezisebenza kahle kakhulu ze-PCB nezindlela zokukhiqiza zinganqunywa. Isikhathi esiningi, ama-prototypes e-PCB enziwa kuzingxenyekazi ezibonakalayo. Kodwa-ke, ngezinhlelo zokusebenza ezinamandla, ama-prototypes we-PCB angakhiwa ukuze avivinye ukusebenza. Uhlobo lwe-PCB lungaba imodeli yedijithali, uhlobo oluthile, noma uhlobo olusebenzayo ngokuphelele (olufanayo). Ngoba i-prototyping bekuwukwamukelwa kokuqala kwe-Manufacture and Design Design (i-DFMA), inqubo yenhlangano ye-PCB inezinzuzo eziningi ngokuhamba kwesikhathi.

Ukubaluleka kokukhiqizwa kwesibonelo ekukhiqizeni i-PCB

Yize abanye abakhiqizi be-PCB beqa ukwenza prototyping ukonga isikhathi sokukhiqiza, ukwenza njalo kuvame ukuphikisana. Nazi ezinye zezinzuzo ze-prototyping ezenza lesi sinyathelo sisebenze noma sibaluleke.

Uhlobo oluthile luchaza ukugeleza kokuklanywa kokukhiqizwa nokuhlanganiswa. Lokhu kusho ukuthi zonke izinto ezihlobene nokukhiqiza kanye nomhlangano zibhekwa kuphela ngesikhathi sokuklanywa kwe-PCB. Lokhu kunciphisa izithiyo ekukhiqizeni.

Ekukhiqizeni kwe-PCB, kukhethwa izinto ezifanele zohlobo oluthile lwe-PCB ngenkathi kwenziwa prototyping. Kulesi sinyathelo, onjiniyela bahlola bese bezama izinto ezahlukahlukene ngaphambi kokukhetha okuyiyona. Ngakho-ke, izinto ezibonakalayo njengokumelana namakhemikhali, ukumelana nokugqwala, ukuqina, njll zivivinywa kuphela ezigabeni zokuqala. Lokhu kunquma ukuthi kungenzeka ukwehluleka ngenxa yokungahambisani nezinto ezibonakalayo ezigabeni zakamuva.

Ama-PCBS ngokuvamile akhiqizwa ngobuningi. Ama-PCBS aklanywa okukodwa asetshenziselwa ukukhiqizwa ngobuningi. Uma ukwakheka kungokwezifiso, amandla wamaphutha wedizayini aphezulu. Uma kwenzeka iphutha lokuklama, iphutha elifanayo liphindwaphindwa ezinkulungwaneni zama-PCBS ekukhiqizeni ngobuningi. Lokhu kungaholela ekulahlekelweni okukhulu, kufaka phakathi okokufaka kwezinto ezibonakalayo, izindleko zokukhiqiza, izindleko zokusebenzisa imishini, izindleko zabasebenzi nesikhathi. I-PCB prototyping isiza ukukhomba nokulungisa amaphutha wedizayini kusenesikhathi ngaphambi kokukhiqizwa.

Imvamisa, uma kutholakala iphutha le-PCB design ngesikhathi sokukhiqiza noma sokuhlangana noma sokusebenza, umklami kufanele aqale phansi. Imvamisa, ubunjiniyela obudingekayo buyadingeka ukuhlola amaphutha kuma-PCBS akhiqizwayo. Ukwenza kabusha nokuzala kabusha kungachitha isikhathi esiningi. Ngoba prototyping ixazulula amaphutha esigabeni sokuklama kuphela, ukuphindaphinda kuyagcinwa.

Zenzelwe futhi zenziwa ukubukeka nokusebenza ngokufanayo ngokuqhathaniswa nezidingo zokugcina zomkhiqizo. Ngakho-ke, ukwenzeka komkhiqizo kuyanda ngenxa yokwakheka kohlobo oluthile.
