Ukuhlaziywa kwezindleko zokukhiqiza ze-PCB ze-Highleap ezinezingqimba ezingu-14 kuchaza izinto ezibangela izindleko zebhodi elingenalutho. Ekuhlanganisweni kwabantu, nikeza i-BOM evunyiwe, isibikezelo senani, ezinye izindlela ezamukelekayo zezingxenye kanye nezidingo zokuhlola zokugcina ukuze ukuthengwa kwezinto kanye nesikhathi sokuhlanganiswa kungalinganiswa ngokukhishwa kwangempela.

Yini enquma intengo kanye neshejuli ye-PCBA ethunyelwe iyonke?

Ishejuli yokukhiqiza yebhodi elihlanganisiwe elinezingqimba eziyishumi nane ihlanganisa ukukhishwa kokwenziwa, ukukhiqizwa nokuhlolwa kwebhodi elingenalutho, ukutholakala kwezingxenye, ukulungiswa kwe-stencil/fixture, ukwenziwa kwe-SMT/THT, uhlelo, ukuhlolwa kokusebenza kanye nokuthunyelwa . Lezi zigaba azihlali zilandelana ngokuqinile: ukuthengwa kwe-BOM okuvunyiwe kungaqala ngesikhathi esifanayo nokwakhiwa kwebhodi elingenalutho, kuyilapho i-fixture yokuhlola ngokwezifiso ingadinga isikhathi sokuhola ngaphambi kokuba amabhodi agcwaliswe. Ikhotheshini kufanele ikhombise indlela ebalulekile nokuthi iyiphi imvume noma ingxenye ephethe ishejuli.

Ukuqhathaniswa kwezindleko okuphelele kufanele kuhlukanise ukwenziwa kwe-PCB, ukutholakala kwe-BOM, ukucutshungulwa kokuhlanganiswa, ukuthuthukiswa kwamathuluzi kanye kanye nokuhlolwa, ukwenziwa kokuhlolwa okuvamile, ukwakheka kwe-coating noma ibhokisi, ukuhlela kanye nokuthutha. Intengo ephansi yebhodi elingenalutho ingase inganikeli izindleko ezivivinywayo ze-PCBA uma umhlinzeki engakwazi ukusekela umsebenzi we-BGA odingekayo, i-fixture noma i-firmware. Isipho se-Highleap esisodwa sinamandla kakhulu uma le mithwalo yemfanelo ingahlanganiswa kuphakheji yokukhiqiza ekhishwe enemingcele ebhalwe ngokucacile.

Yini edingekayo ukuze uthole isilinganiso sokukhiqiza esikhundleni sesilinganiso sokuhlanganiswa esingahleliwe?

Thumela amafayela e-Gerber/ODB++ alawulwayo kanye ne-stackup evunyiwe; ama-callout okubhoboza kanye nokugcwalisa nge-with; i-BOM ephelele kanye ne-AVL; idatha ye-centroid/yokubeka; imikhawulo yenqubo yokudweba kanye ne-solder; imiyalelo ye-firmware kanye nokuhlela; isisetshenziswa sokuhlola noma imininingwane yokusebenza; inani lesampula/lokukhiqiza; kanye nemigomo yokupakisha/yokuya. Sho ukuthi yimiphi imisebenzi ekhethekile eyimpoqo nokuthi yimiphi engakhetha kuyo. Impendulo ingabe ihlukanisa izinto zenkampani ku-NRE engaxazululiwe noma umsebenzi wokufaneleka.

Cela Isilinganiso Esiphelele Sokuhlanganiswa Kwe-PCB Esinezingqimba Eziyi-14

Ukuze uthole ikhotheshini ehlanganisiwe, thumela i-Gerber/ODB++ noma i-IPC-2581, amafayela okubhoboza kanye nezici ezikhethekile, imininingwane ye-stackup kanye ne-finish evunyiwe enezingqimba ezingu-14, i-BOM enezinombolo zezingxenye zomkhiqizi, izikhundla ze-centroid/XY, imidwebo yokuhlanganisa, izinhlobo ezifakiwe/ze-DNP, imiyalelo ye-firmware noma yokuhlela kanye nezinqubo zokuhlola ukusebenza ezitholakalayo. Khombisa inani le-prototype kanye nokukhiqiza, indawo yokulethwa, ubunikazi bezingxenye kanye nezidingo ezikhethekile zokupakisha.

I-Highleap ingachaza umzila webhodi elingenalutho kanye nomsebenzi webhodi elinabantu abaningi ngesiphakamiso esisodwa, kanye nemingcele yokuhlola okuvunyelwene ngayo kanye nokuhlolwa okuqoshiwe ngaphambi kokukhishwa.
