Ukuthuthukisa Izindleko Zokukhiqiza ze-PCB: Ukulungiswa Kwedizayini Ukuze Kuthuthukiswe Ukusebenza Kakuhle Kokukhiqiza

Kubaklami be-PCB, ukuqonda ukuthi ukukhetha okukhethekile okuklamayo kunomthelela kanjani ekwenzeni kungavumela ukulungiswa kwamasu ukuze kwehliswe izindleko zokukhiqiza nokwenza lula ukwenziwa. Ukuhlaziywa okulandelayo kunikeza ukubuka okujulile kokuthi izici zedizayini zinethonya kanjani izinselele zokukhiqiza nezindleko, kanye nezinguquko ezingokoqobo zedizayini zokuthuthukisa izindleko nokusebenza kahle kokukhiqiza.

1. Usayizi we-PCB kanye nesu lokuhlanganisa

Usayizi we-PCB nokufakwa kwephaneli okusebenzayo kubalulekile ekulawuleni izindleko, ikakhulukazi ekukhiqizeni umthamo omkhulu:

• Iphaneli Ukusebenza kahle: Ukwandisa inani lamabhodi kuphaneli eyodwa kuthuthukisa ukusetshenziswa kwezinto futhi kunciphisa izindleko zeyunithi ngayinye. Imiklamo efanayo engunxande, lapho kungenzeka khona, ingathuthukisa ukusetshenziswa kwamaphaneli futhi inciphise udoti.
• Izithiyo Zempahla Nokuqina: Ezinye izinto zokwakha, njenge-laminate ekhethekile ephansi yokulahlekelwa, zinemikhawulo ethile yosayizi wephaneli. Ubukhulu bebhodi buthinta nesikhala kumaphaneli, ngamabhodi amakhulu adinga isikhala esithe xaxa phakathi kwamayunithi, okungenzeka ukuthi kunciphisa isivuno ngephaneli ngayinye.
• Izici ze-Edge kanye ne-Component Overhang: Imiklamo enezixhumi ezinqenqemeni (isb., iminwe esagolide) noma izingxenye ezidlulela ngale konqenqema lwebhodi zidinga isikhala esengeziwe kuphaneli, kunciphisa ukusebenza kahle kwamaphaneli. Ukuthutha izingxenye noma ukulungisa imiklamo yesixhumi kungasiza ukonga isikhala samaphaneli.

Lapho abaklami bethuthukisa usayizi we-PCB, ukuhlelwa kwephaneli, nesakhiwo, bangakhuphula isivuno sezinto ezibonakalayo kanye nezindleko eziphansi zebhodi ngalinye, ikakhulukazi ekukhiqizweni kwenqwaba. Ukulungisa izici zonqenqema, ukujiya, kanye nokuma kwengxenye kungathuthukisa nakakhulu ukusetshenziswa kwamaphaneli futhi kunciphise udoti.

2. Ukukhethwa Kwezinto Ezisetshenziswayo kanye Nezinye Izindlela Ezingabizi kakhulu

Ukukhethwa kwezinto kuthinta izindleko zokukhiqiza, ukuqina, nokusebenza. Ukukhetha izinto ezifanele zezendlalelo ezithile kunganikeza ukonga izindleko:

• Ukusetshenziswa Kwezinto Ezihlosiwe: Icacisa izinto ezisebenza kakhulu ezifana i-laminate ekhethekile yokulahlekelwa okuphansi or PTFE kuphela ezendlalelo ezibucayi, kuyilapho kusetshenziswa i-FR-4 evamile kwezinye izendlalelo, kunciphisa izindleko zempahla ngenkathi kuhlangatshezwana nezidingo zokusebenza.
• Ukuthuthukisa Isisindo Sethusi kanye Prepreg: Ikhopha esindayo inyusa kokubili izindleko zempahla nezinqubo ngenxa yokuqoshwa okude kanye nokusetshenziswa kwe-prepreg eyengeziwe. Ukunciphisa isisindo sethusi ezingqimbeni ezingabalulekile kunciphisa lezi zindleko.
