1. Kurongeka maererano nematunhu modules, uye matunhu ane hukama anoona basa rimwe chete anonzi module. Izvo zvikamu zviri mudutu redunhu zvinofanirwa kutora musimboti wekusangana kwepedyo, uye dhijitari redunhu uye analog dunhu rinofanira kuparadzaniswa;
2. Hapana zvikamu kana michina ichaiswa mukati me1.27mm yemakomba asingakwiri akadai semakomba ekumisikidza, maburi akajairika, uye 3.5mm (yeM2.5) uye 4mm (yeM3) ye3.5mm (yeM2.5) uye 4mm (yeM3) haizobvumirwi kuisa zvikamu;
3. Dzivisa kuisa vias pasi horizontally akatasva resistors, inductors (plug-ins), electrolytic capacitors uye zvimwe zvinoriumba kuti vadzivise pfupi-circuiting ari vias uye chikamu dzimba pashure mafungu soldering;
4. Nharaunda pakati pekunze kwechikamu uye kumucheto kwebhodhi ndeye 5mm;
5. Chinhambwe chiri pakati pekunze kwechigadziko chechikamu chinosungirirwa uye kunze kwechikamu chinopindirana chiri pedyo chakakura kudarika 2mm;
6. Metal shell components uye metal parts (shielding boxes, etc.) haigoni kubata zvimwe zvikamu, haigoni kuva pedyo nemitsetse yakadhindwa, mapedhi, uye nzvimbo yavo inofanira kuva yakakura kudarika 2mm. Saizi yemakomba ekumisikidza, maburi ekuisa mabheji, maburi oval uye mamwe makomba akaenzana mubhodhi kubva kumucheto kwebhodhi yakakura kupfuura 3mm;
7. Chinhu chinopisa hachifaniri kunge chiri pedyo netambo uye chinhu chinopisa chinopisa; iyo yepamusoro-inopisa mudziyo inofanira kugoverwa zvakaenzana;
8. Chigadziko chemagetsi chinofanira kurongedzerwa kumativi ebhodhi rakadhindwa sezvinobvira, uye chigadziko chemagetsi uye chigadziko chebhasi chebhasi chakabatanidzwa nacho chinofanira kurongwa kune rumwe rutivi. Kunyanya kuchenjerera kunofanira kutorwa kusaronga zvigadziko zvemagetsi uye mamwe mawelding anobatanidza pakati pezvibatanidza kuti zvive nyore kusungirirwa kwezvigadziko izvi uye zvibatanidza, pamwe chete nekugadzirwa uye kusungirirwa kwetambo dzemagetsi. Kurongeka kwepakati pezvigadziko zvemagetsi uye welding zvinobatanidza zvinofanirwa kutariswa kufambisa plugging uye kuburitsa kwemagetsi plugs;
9. Kurongeka kwezvimwe zvikamu: Zvose zvikamu zve IC zvakagadzirirwa kune rumwe rutivi, uye polarity yezvikamu zvepolar inonyatsoratidzwa. Iyo polarity yebhodhi rakadhindwa rimwechete haigone kuratidzirwa kupfuura nzira mbiri. Kana mativi maviri aonekwa, iwo maviri mafambiro ari perpendicular kune mumwe nemumwe;
10. Iyo wiring pabhodhi yepamusoro inofanira kuva yakaoma uye yakaoma. Kana iyo density mutsauko wakakura kwazvo, inofanirwa kuzadzwa ne mesh mhangura foil, uye gidhi inofanira kunge yakakura kupfuura 8mil (kana 0.2mm);
11. Panofanira kunge pasina kuburikidza nemakomba pane SMD pads kudzivirira solder paste kurasikirwa uye nhema soldering yezvikamu. Mitsetse yakakosha yechiratidzo haibvumidzwe kupfuura pakati pepini yesokisi;
.
13. Nesezvinogoneka, michina yepolarized inofanirwa kuenderana neiyo polarity yekumaka kutungamira pabhodhi rimwechete.
