Mokhoa oa ho thibela liketsahalo tse tšeletseng tsa khokahano ea thini ho boto ea potoloho kamora ho ts’oaroa ka leqhubu.

1.Ka lebaka la ts’ebetso ea khokahanyo ea thini e bakoang ke phini e telele haholo ea motsoako nakong ea ts’ebeliso ea leqhubu la boto ea potoloho, tlhokomelo e tla fuoa bolelele ba bolelele ba phini ea motsoako ka kakaretso e leng 1.5-2mm, e ke keng ea etsahala haeba e sa fete bophahamo bona. .

2. Hobane moralo oa ts’ebetso ea PCB o ntse o rarahana le ho feta mme phapang ea lead e ntse e teteana le ho feta, ts’ebetso ea khokahanyo ea thini kamora ho ts’oaroa ha leqhubu e etsahala. Ho fetola moralo oa pad ke tharollo. Mohlala, ho fokotsa boholo ba pad, ho eketsa bolele ba pad e tsoang ka lehlakoreng la leqhubu, ho eketsa ts’ebetso ea ts’ebetsong / ho fokotsa bolelele ba katoloso ea lead le tsona ke tharollo.

3. Kamora ho qhibilihisa maqhubu, thini e qhibilihisitsoeng e kenella ka holim’a boto ea potoloho ho theha khokahano ea thini lipakeng tsa lithakhisa tsa karolo. Lebaka le ka sehloohong la ketsahalo ena ke hore bophara ba kahare ba sebaka se se nang letho bo boholo haholo, kapa bophara ba kantle ba phini ea motsoako bo nyane haholo.

4. Karolo ea leqhubu e entsoeng ka likarolo tsa maoto a teteaneng libakeng tse peli e hokahane le thini kamora ho tjheseletsa.

5. Ho qabella ka leqhubu ka thini ka lebaka la boholo ba pad.

6. Khokahano ea thini ea lithakhisa tsa motsoako kamora ho ts’oaroa ka leqhubu ka lebaka la ho se sebetse hantle ha lithakhisa tsa motsoako.

Mokhoa oa ho thibela khokahano ea thini ea boto ea potoloho kamora ho ts’oaroa ka leqhubu.

1. Design ho latela PCB moralo ga tlhaloso. The selekane telele tsa dita bofelo tse peli li tla ba perpendicular ho tataiso tjheseletsa, le selekane telele bakeng SOT le SOP tla tšoanang le tataiso ea tjheseletsa. Atolosa sebaka sa pini ea ho qetela ea SOP (rala sethala sa solder);

2. Lithakhisa tsa likarolo tse kentsoeng li tla theoa ho latela likheo tsa sekoti le litlhoko tsa kopano tsa boto e hatisitsoeng. Haeba ts’ebetso e khuts’oane ea ho kenya litšepe e amoheloa, lithakhisa tsa karolo e holim’a bokaholimo ba tjheseletsa li tla pepesetsoa bokaholimo ba boto e hatisitsoeng ka 0.8 ~ 3mm, mme mmele oa karolo o tla ema hantle nakong ea kenyelletso;

3.Seta mocheso preheating ho ea ka boholo ba PCB, hore na ho na le mapolanka multilayer, palo ea dikarolo, palo ea dikarolo mounted, joalo-joalo;

4. Mocheso oa leqhubu la thini ke 250 ± 5 ℃, ‘me nako ea ho tjheseletsa ke 3 ~ 5S. Ha mocheso o le tlase hanyane, lebelo la lebanta le tsamaisang thepa le lokela ho tsamaea butle;
