Mukupfekedzwa kwemhangura, kuti tiwane mhedzisiro yainoda yemhangura, isu tinofanirwa kutarisisa kune izvo nyaya: 1. Kana pane zvikonzero zvakawanda paPCB, zvakadai seSGND, AGND, GND, nezvimwewo, maererano nenzvimbo dzakasiyana dzePCB pamusoro, iyo inonyanya kukosha "ivhu" inoshandiswa sechirevo chekuzvimiririra kuvhara mhangura, ivhu redhijitari. uye analog pasi.Iko hakuna zvakawanda zvekutaura pamusoro pemhangura yemhangura zvakasiyana.Panguva imwecheteyo, pamberi pehuputi hwemhangura, mitsara yemagetsi inowirirana inotanga kuomeswa: 5.0V, 3.3V, nezvimwewo. Nenzira iyi, maitiro akawanda akaremara emhando dzakasiyana anoumbwa.

2. Kune imwe-point yekubatanidza kwezvikonzero zvakasiyana, nzira ndeyekubatanidza kuburikidza ne0 ohm resistance kana magnetic beads kana inductance. 3. Copper cladding pedyo nekristaro oscillator.Iyo crystal oscillator mudunhu ndeye yakakwira-frequency emission sosi.Iyo nzira ndeyekupfekedza mhangura yakatenderedza crystal oscillator, uye wobva wagadzika goko rekristaro oscillator zvakasiyana. 4. Dambudziko rechitsuwa (dead zone), kana iwe uchifunga kuti rakakura, saka hazvizoiti mari yakawanda kutsanangura pasi kuburikidza uye kuwedzera. 5. Pakutanga kwetambo, tambo yepasi inofanira kubatwa zvakaenzana, uye tambo yepasi inofanira kuendeswa zvakanaka kana ichifamba.Iwe haugone kuvimba nekuwedzerwa kwevias mushure mekuputira mhangura kuti ubvise pini yepasi yekubatanidza.Mhedzisiro iyi yakaipa kwazvo. 6. Zvakanakisisa kuti usava nemakona akapinza pabhodhi ( 7. Usadururira mhangura munzvimbo yakazaruka ye wiring mukati mechikamu chepakati pe-multi-layer board.Nokuti zvakanyanya kuoma kuti iwe uite iyi mhangura idire "pasi rakanaka". 8. Masimbi mukati memudziyo, akadai sesimbi inopisa sinks, simbi yekusimbisa mbariro, nezvimwewo, inofanira kuva "yakanyatsodzika". 9. Chivharo chekupisa chesimbi chetatu-terminal voltage stabilizer inofanira kunge yakanyatsogadziriswa.Ivhu rekuzviparadzanisa bhandi pedyo nekristaro oscillator rinofanira kunge rakanyatsodzika.Mune izwi: kana iyo mhangura yakashongedzwa paPCB ikabatwa nemazvo, ichave "pros inodarika iyo cons".Inogona kuderedza nzvimbo yekudzoka yemutsara wechiratidzo uye kuderedza kupindira kwemagetsi kwechiratidzo kune kunze.
