Ukuba wenza eyakho PCB layout, being prepared may just help you organize and remember important design details. Nangona kunjalo, ukuba uyilo luthunyelwe komnye umntu kubeko, oku kungabikho kwamalungiselelo kunokubangela iingxaki ezinkulu ekugqibezeleni uyilo.

Makhe sijonge ezinye zezinto ekufuneka sizithathele ingqalelo kwisikimu sokwenza kube lula ukutshintsha ubeko lwePCB.

Uguqula njani ubeko lwePCB? Umthetho wokuqala: Amaxwebhu acocekileyo Clean

Uyilo lwesekethe lungavela kumanqaku abhaliweyo kwiphepha, okanye kwizikimu ezotywe ngokungxama ebhodini, kodwa ke ezi azibhalwanga ngokufanelekileyo. Many medical institutions are now forcing doctors to electronically file prescriptions instead of writing them down with pen and paper, so patients can read them easily.

Njengoko kubalulekile ukuba ukwazi ukufunda imigqaliselo ngokuchanekileyo, kunjalo ke nokufunda ulwazi kunye nemiyalelo evela kwisikimu. Ngaba uzenzele inceba kwaye uthathe ixesha lokuqinisekisa ukuba i-schematics iyafundeka.

Here are some tips on how to do it correctly:

Sebenzisa iigridi ukulungelelanisa iisimboli, ukuzoba imigca, kunye nokucwangcisa isicatshulwa.

Ifonti yokubhaliweyo kunye nobubanzi bomgca kufanele ukuba bube bukhulu ngokwaneleyo ukuba kube lula ukufundwa, kodwa bungabi bukhulu kangako kangangokuba bube budide ubuchwephesha.

Don’t crowd symbols and text together; leave some space for them so they can be read accurately.

Bhala izikram ngokuhamba okunengqiqo okunengqiqo. Akukho sidingo sokuba izinto zinamathele kwingingqi; zinokuthintelwa ukuba nje azingobabo.

Ukuba unokwenza amaxwebhu afundekayo, awunakukhathazeka ngokusebenzisa amanye amaphepha kwisikimu sakho.

If you give yourself enough time to create easy-to-use documents, you’ll get a lot of benefit from that extra effort during the layout process.

Iindawo zethala leencwadi zibalulekile ekuguquleni ubeko lwePCB

Elinye icandelo elibalulekileyo lokuguqula ngempumelelo izakhelo zibe zizakhiwo zePCB kukuqinisekisa ukuba iindawo zethala leencwadi zihlaziyiwe kwaye zichanekile. What the symbol represents must be correct. Oku kubandakanya izikhonkwane, isicatshulwa, imilo, kunye neempawu. Ngamanye amaxesha abantu basebenzisa iisimboli ezikhoyo njengeetemplate ukwakha ezitsha, emva koko bangakunaki ukongeza, ukucima, okanye ukulungisa iinxalenye zomyalezo wokuqala. Ngcono okwangoku, kunokubakho ukudideka okuninzi xa inani leenxalenye kumzobo wesikimu lingahambelani nenxalenye yenxalenye exelwe kwingxelo. The worst case scenario is that the symbolic information is completely wrong and leads to a connection error in the schematic or downstream tool, such as the emulator.

Xa usakha uphawu olutsha kuyilo lwakho, qiniseka ukuba ubandakanya lonke ulwazi lwecandelo elifanelekileyo. Oku kuyakubandakanya isixhobo sokwakheka kwegama lendawo ebonakalayo, inombolo yenxalenye yenkampani, inombolo yenxalenye yomthengisi, ulwazi ngeendleko kunye nedatha yokulinganisa. Yonke inkampani inemigangatho yayo yoko kufanelekileyo okanye ekungafanelekanga ukuba ibandakanywe kwicandelo lethala leencwadi, kodwa ukuba nolwazi oluninzi kulunge kunokuba nokuncinane. Xa ugqibile, qiniseka ukuba ugcwalisa indawo entsha kunye nelayibrari yecandelo elifanelekileyo kwaye iinxalenye kwiskimatic zihlaziywa ukubhekisa kwilayibrari echanekileyo.

Detailed and complete schematic information is important

Njengokuba kungekho lwazi lungako kumacandelo elayibrari, kuyafana nakwisikimu. Be careful not to add so much data that the schematic becomes difficult to read, but add enough information to help downstream with layout, testing, and rework. Nayi eminye imizekelo yolwazi olufanelekileyo:

Identification of schematic functional areas (” power supply “, “fan control”, etc.).

Vavanya isikhundla sonikezelo lwamandla, isiseko okanye imiqondiso ethile.

Ukubekwa kwezinto ezinzileyo ezinje ngezihlanganisi kunye neeplagi.

Izixhobo zihlelwe ukuba zichonge isantya esiphezulu okanye iindawo ezibekiweyo ezibuthathaka.

Iisekethe ezinobuthathaka ezinokufuna ingqalelo ekhethekileyo, ezinje nge-RF yokukhusela.

Iindawo ezishushu ezixhalabisayo.

Iimfuno zesantya esiphakamileyo, ezinje ngokulinganisa ubude beentambo okanye iintambo zolawulo lwe-impedance.

Isibini esahlukileyo.

In addition to the functional information listed above, don’t forget to include all the general schematic document data. Oku kuya kubandakanya izinto kwibar yomxholo, njengegama lenkampani, inombolo yenxalenye, uhlaziyo, igama lebhodi, umhla kunye nolwazi lobunikazi. Ngokuqinisekisa ukuba unolwazi olwaneleyo kwiskimu kunye nedatha eninzi kangangoko, kodwa ingabi luxanduva kakhulu, iyanceda ukuqinisekisa ukuguqulwa okuyimpumelelo kwesikimu kuyilo lwePCB.
