1. Ngati alipo ambiri PCB nthaka, SGND, AGND, GND, ndi zina zotero, nkofunika kugwiritsa ntchito “nthaka” yofunikira kwambiri monga kutchula mkuwa mosasunthika molingana ndi bolodi la PCB. N’zosavuta kunena kuti nthaka ya digito ndi nthaka ya analog imagwiritsidwa ntchito mosiyana ndi zokutira zamkuwa. 5.0V, 3.3V, ndi zina zotero, mwanjira iyi, mapangidwe angapo amapangidwe amitundu yosiyanasiyana amapangidwa.

2, yolumikizira mfundo imodzi, njirayo imadutsa 0 ohms kukana kapena maginito mikanda kapena kulumikizana kwa inductance;

3, galasi oscillator pafupi coating kuyanika mkuwa, ndi oscillator galasi mu dera ndi mkulu pafupipafupi umuna gwero, njira ndi kuzungulira galasi oscillator coating kuyanika mkuwa, ndiyeno galasi oscillator chipolopolo payokha pansi.

4, vuto la chilumbachi (ngati chakufa), ngati likumva kukhala lalikulu kwambiri, ndiye kuti tchulani bowo kuti liwonjezere silivuto lalikulu.

5, kumayambiriro kwa waya, iyenera kukhala yofanana pansi, pomwe waya ayenera kukhala wabwino, sangadalire zokutira zamkuwa powonjezera mabowo kuti athetse kulumikizana kwa pini, zotsatirazi ndizoyipa kwambiri.

6, pagululo sibwino kukhala ndi Angle yakuthwa (= 180 madigiri), chifukwa kuchokera pakuwona kwa ma elekitiroma, ichi ndi antenna yotumiza!

7, wosanjikiza wapakatikati wosanjikiza wiring lotseguka, osagwiritsa ntchito mkuwa. Chifukwa ndizovuta kupanga phukusi lamkuwa ili “lokhazikika”.

8, chitsulo mkati mwa zida, monga radiator yachitsulo, chingwe cholimbitsa chitsulo, chiyenera kukwaniritsa “maziko abwino”.

9, atatu osachiritsika yang’anira ya kutentha madyaidya ndikuledzera chipika, ayenera kukhala nthaka yabwino. Lamba lodzipatula pafupi ndi oscillator wa kristalo liyenera kukhala lokhazikika. Mwachidule: zokutira zamkuwa pa PCB, ngati vuto lokhazikika lathandizidwa bwino, ndi “labwino kwambiri kuposa loyipa”, lingachepetse malo obwerera kumbuyo kwa mzere wazizindikiro, kuchepetsa chizindikiritso chakunja kwamagetsi.
