I roto i te whakakikorua parahi, ki te whakatutuki i te painga e hiahiatia ana o te kapi parahi, me aro tatou ki enei take: 1. Mena he maha nga waahi kei runga i te PCB, penei i te SGND, AGND, GND, me etahi atu, i runga i nga waahi rereke o te mata PCB, ko te "whenua" tino nui ka whakamahia hei tohutoro ki te hipoki motuhake i te parahi, te whenua mamati. me te whenua tairitenga.Kaore he korero nui mo te paninga parahi motuhake.I te wa ano, i mua i te paninga parahi, ka whakapakeketia nga raina hiko e rite ana: 5.0V, 3.3V, me etahi atu. I tenei ara, he maha nga hanganga rereke o nga ahua rereke ka hangaia.

2. Mo te hononga ira-kotahi o nga papa rereke, ko te tikanga ko te hono ma te 0 ohm parenga, pirepire autō ranei, inductance ranei. 3. Ko te whakakikorua parahi e tata ana ki te oscillator tioata.Ko te oscillator tioata i roto i te ara iahiko he puna tukunga auau teitei.Ko te tikanga ko te whakakakahu i te parahi ki te taha o te oscillator karaihe, katahi ka werohia te anga o te oscillator karaihe. 4. Te raruraru o te motu (rohe mate), ki te whakaaro koe he nui rawa, karekau he utu nui ki te tautuhi whenua ma te taapiri. 5. I te timatanga o te waea, kia rite te whakahaere i te waea whenua, me te waea whenua kia pai te rere i te wa e ararere ana.Kaore e taea e koe te whakawhirinaki ki te taapiri o te vias i muri i te paninga parahi hei whakakore i te titi whenua mo te hononga.He tino kino tenei paanga. 6. He pai ake kia kaua e whai koki koi ki runga i te papa ( 7. Kaua e ringihia te parahi ki te waahi tuwhera o te waea i roto i te paparanga waenga o te papa-papa-maha.Na te mea he tino uaua ki a koe te mahi i tenei parahi kia ringihia "te whenua pai". 8. Ko nga konganuku kei roto i te taputapu, penei i te totohu wera whakarewa, nga tutaki whakarewa, me etahi atu, me "whakapapa pai". 9. Ko te poraka whakarewa wera o te whakapumau ngaohiko ngaohiko e toru-waahi me pai te whenua.Ko te whitiki wehe whenua e tata ana ki te oscillator tioata me pai te papa.I roto i te kupu: ki te pai te mahi i te whakakikorua parahi i runga i te PCB, ka tino "pai ake i te kino".Ka taea e ia te whakaiti i te waahi hokinga o te raina tohu me te whakaiti i te pokanoa hiko o te tohu ki waho.
Kia mohio ki a matou, clink konei .
