Multilayer e rarahaneng le HDI li hloka bonyane linako tsa ts'ebetso ho sa tsotelehe hore na ho potlakile hakae.

5.4 Lintho Tse Loketseng Boleng

Tlhahiso e potlakileng e eketsa kotsi. Bahlahisi ba nang le botumo ba boloka maemo a boleng empa ba ka fokotsa dikgetho tsa maeto ho ena le ho beha boleng kotsing. O se ke wa tela boleng ka lebaka la lebelo—ho hloleha ha masimo ho bitsa chelete e ngata ho feta tieho ya kemiso.

Hlahloba Linako tsa Hona Joale tsa ho Etella Pele

6. Ho rera Phepelo e Boleloang esale pele

Ho rera esale pele ho felisa mathata a mangata a nako ea pele.

6.1 Kemiso ea Sebele

Haha linako tsa sebele u sebelisa linako tse tloaelehileng tsa ho etella pele hammoho le maemo a tšohanyetso. Mohlala o tloaelehileng: matsatsi a 7-10, eketsa maemo a tšohanyetso a matsatsi a 3-5. Tlhahiso e tloaelehileng: matsatsi a 14-21, eketsa maemo a tšohanyetso a matsatsi a 5-7. Meaho ea pele: Eketsa nako e eketsehileng bakeng sa mathata a ka bang teng.

6.2 Temoho ea Tsela ea Bohlokoa

Hlalosa hore na ke eng e hlileng e leng ea bohlokoa ka nako. Hangata, kopano le teko li telele ho feta tlhahiso ea PCB. Hangata linako tsa ho etella likarolo li feta linako tsa ho etella boto. U se ke ua potlakela ho etsa tlhahiso ea PCB haeba likarolo li sa fihle ka libeke.

6.3 Puisano ea Mofani oa Thepa

Boloka moetsi oa hau a tsebisoa ka merero e tlang le likhakanyo tsa bophahamo ba modumo, liodara tsa bohlokoa ba kemiso, liphetoho tse ka bang teng tsa moralo, le litlhoko life kapa life tse khethehileng.

Highleap Electronics e fana ka likhakanyo tsa nako ea ho etella pele nakong ea ho qotsa, lintlafatso nakong ea tlhahiso, le puisano e sebetsang haeba ho hlaha mathata.

6.4 Bakeng sa Merero ea Kopano

Haeba projeke ea hau e kenyelletsa kopano, nako eohle ea ho etella pele e kenyelletsa tlhahiso ea PCB, ho fumana likarolo (hangata karolo e telele ka ho fetisisa), nako ea ho etella pele kopano ea PCB , le liteko le thomello.

Bakeng sa likopano tse felletseng tse potlakileng, sheba likhetho tsa rona tsa nako ea ho etella pele ea PCBA.

Ikopanye le sehlopha sa rona ho buisana ka litlhoko tsa nako ea hau le ho theha kemiso ea tlhahiso e sebetsang bakeng sa projeke ea hau.
