Inovimbisa kugadzikana uye inoderedza ruzha mu12-layer PCBs yechiratidzo chakasimba, yakakwira voltage application.

Mabhodhi edunhu ndiwo musana wechero mudziyo wemagetsi, unotsigira kuyerera kwezviratidzo uye simba. Zvisinei,kana zvasvika kune dzakaoma dhizaini senge 12-layer mabhodhi anoshandiswa mukutemesa chiratidzo chekufambisa uye yakakwira-voltage application, kugadzikana kwemagetsi uye ruzha nyaya dzinogona kunetsa. Mune ino blog post, isu tichaongorora mhinduro dzinoshanda dzekugadzirisa idzi nyaya uye tive nechokwadi chekushanda kwakakwana.

Simba rekupa kugadzikana kwakakosha mumaseketi emagetsi, sezvo kuchinjika kana kukanganisa kunogona kukonzera kusashanda zvakanaka kana kukuvara zvachose.Saizvozvowo, ruzha runogona kukanganisa kutapurirana kwechiratidzo, zvichikonzera kukanganisa uye kuderedza kushanda kwese system. Nekutevera iyi nhungamiro, unogona kuvandudza mashandiro uye kuvimbika kana uchishandisa 12-layer redunhu mabhodhi mune inonzwisa tsitsi.

1. Ronga kugovera kwemagetsi zvakakwana:Kugovera simba kwakafanira kwakakosha pakugadzirisa kugadzikana uye nyaya dzeruzha. Tanga nekunyatsoongorora zvinodiwa nemagetsi edunhu uye kugadzira zano rekugovera rine kufunga. Ziva akakosha masimba emasimba uye ona kuti vakatsaurira ndege dzemagetsi kana kugovera magetsi emagetsi. Kuzviparadzanisa nevamwe kunobatsira kudzivirira ruzha kubva kune chimwe chikamu chinovhiringidza chimwe, nokudaro kuderedza mukana wehuori hwechiratidzo.

2. Gadzirisa decoupling capacitors:Decoupling capacitors inoita basa rakakosha mukudzikamisa magetsi uye kuderedza ruzha. Aya ma capacitor anochengeta simba remagetsi uye anorisunungura panguva yazvino zvinodikanwa, kuve nechokwadi chakagadzikana mazinga emagetsi. Kuti uwedzere kudhirowa, zvine hungwaru isa capacitor padyo nesimba uye pasi mapini ezvimedu zvinonzwisisika. Musanganiswa weyakaderera uye yakakwira kukosha capacitors mune yakanyatso kurongwa network inopa inobudirira decoupling pane yakafara frequency renji.

3. Kungwarira kwechikamu kuiswa:Kuiswa kwechikamu chinhu chakakosha chekudzikisa ruzha. Tanga nekuisa ma-high-frequency components, senge oscillators uye majenereta ewachi, pedyo nemagetsi emagetsi sezvinobvira. Izvi zvikamu zvinonyanya kubatwa neruzha, uye kuzviisa pedyo nemagetsi kunoderedza mukana wekubatanidza ruzha. Saizvozvowo, chengetedza zvinhu zvine hunyoro kure nezvinoita ruzha, masimba epamusoro-soro, kana zvimwe zvingangoitika zvekukanganisa.

4. Layer stacking kufunga:Yakakodzera layer stacking kumisikidza yakakosha kudzikamisa ruzha uye simba rekufambisa nyaya. Funga kuwedzera simba rakatsaurirwa uye ndege dzepasi pakati pezviratidziro kuti uvandudze kutendeseka kwechiratidzo uye kuderedza crosstalk. Pamusoro pezvo, kupatsanura yakakwira-voltage traces kubva kune inonzwisisika masaini maratidziro nekuaisa pamatanho akasiyana anobatsira kudzivirira kubatanidza ruzha. Paunenge uchitarisa yakanakisa stack-up kumisikidza, zvinobatsira kushanda neane ruzivo PCB mugadziri.

5. Inodzorwa impedance dhizaini:Impedance mismatch inogona kuunza zviratidzo zvechiratidzo uye kuderedza kushanda. Mukufambisa kwechiratidzo chekufambisa, kudzora impedance kunova kwakakosha. Ita shuwa kuti masaini echiratidzo ane hupamhi chaihwo, nzvimbo, uye ukobvu hwemhangura kuti uwane iyo impedance inodiwa. Nekuchengetedza inodzorwa impedance mukati medunhu rese, unogona kuderedza kukanganiswa kwechiratidzo uye kugadzirisa kutendeseka kwedata.

6. Inoshanda EMI/EMC kudzivirira:Electromagnetic interference (EMI) uye electromagnetic kuenderana (EMC) inogona kukanganisa zvakanyanya kuita kwedunhu. Shandisa maconductive enclosure kudzivirira zvinhu zvinonzwisa tsitsi kana kushandisa simbi yakavharidzirwa magaba kudzikisa mhedzisiro yeEMI. Pamusoro pezvo, shandisa nzira dzakakodzera dzekudzika senge nyeredzi pasi kana kushandisa ndege yepasi kuti uwedzere kudzikisira nyaya dzeruzha.

7. Kuongororwa kwakadzama uye kuongorora:Mushure mekunge bhodhi redunhu ragadzirwa, kuyedzwa kwakazara kunoitwa kuti kuone kushanda kwayo. Shandisa zvishandiso zvakaita seoscilloscopes, spectrum analyzers, uye chiratidzo chekuvimbika software kuongorora mhando yechiratidzo, kugadzikana kwesimba, uye mazinga eruzha. Ziva chero nzvimbo dzekunetseka uye gadzirisa dhizaini yako zvinoenderana. Kuburikidza nekudzokorora kuyedzwa uye ongororo, unogona kuwana kugadzikana kwako kwakanaka uye kuita ruzha.

Nekutevera nhungamiro idzi, unogona kunyatsogadzirisa kugadzikana kwesimba uye nyaya dzeruzha pamabhodhi gumi nemaviri edunhu, kunyanya mukutepfenyura kwechiratidzo chekufambisa uye yakakwirira-voltage application. Rangarira kuti kuronga kwakaringana, kugovanisa simba kwakaringana, dhizaini yakagadziridzwa, smart componement kuiswa, uye stacking mafungidziro anoita basa rakakosha mukuona kuita kwakaringana kwedunhu. Naizvozvo, isa nguva nesimba munzvimbo idzi kugadzira yakasimba uye yakavimbika PCB dhizaini.
