Hang ha moralo oa PCB o phethiloe, re hloka ho o hlahloba bakeng sa likarolo tsohle tsa projeke.Joalo ka ha re qeta pampiri ea tlhahlobo ka borona, re lokela ho etsa tlhahlobo e bonolo le ho hlahloba mathata a eona hape, e le ho netefatsa hore re ke ke ra etsa phoso e kholo ka lebaka la bohlasoa.Tse latelang neoden mounter baetsi ba ho hlalosa mokhoa oa ho rarolla PCBA sebetsa e khutšoanyane oa potoloho liphoso tse amanang le tsebo.
1. Bula moralo oa PCB k'homphieutheng, marang-rang a nakoana a khantšitsoe, bona hore na ke sebaka sefe se haufi ka ho fetisisa, se nang le monyetla oa ho hokahanya le sengoathoana.Ela hloko ka ho khethehileng potoloho e khutšoanyane ea IC.Haeba manual soldering, ho hlaolela mekhoa e metle:.
2. Pele soldering ho ka bowena pono hlahloba PCB boto hang, 'me sebelisa multimeter ho hlahloba lipotoloho senotlolo (haholo-holo phepelo ea matla le fatše) hore na nako e khutšoanyane ea potoloho.
3. Nako le nako ka mor'a ho tjheseletsa chip ho sebelisa multimeter ho lekanya phepelo ea matla le fatše hore na ho na le potoloho e khutšoanyane.
4. PCBA tlhahiso soldering nako u se ke ua fling tšepe, ka phoso fling solder ho maoto a chip ea soldering (haholo-holo likarolo tsa tafole sticker), ha ho bonolo ho fumana ketsahalo e khutsoanyane potoloho.Nka boto ho khaola mohala (haholo-holo o loketseng boto e le 'ngoe / habeli), khaola mola ka mor'a hore karolo e' ngoe le e 'ngoe ea li-blocks tse sebetsang e matlafatsoe,' me butle-butle e felisoe.
5. Tšebeliso ea lisebelisoa tsa tlhahlobo ea sebaka se khuts'oane.
6. PCBA chip processing BGA chip, ka lebaka la hore manonyeletso ohle a solder a koahetsoe ke chip e sa bonahaleng, le boto ea li-multi-layer (mekhahlelo e fetang 4), joale ho molemo ho arola matla a matla ho moralo oa chip ka 'ngoe, ka sefaha sa makenete kapa 0 ohm khokahano ea letsatsi ea motlakase, e le hore ho be le phepelo ea motlakase e nang le potoloho e khuts'oane ho ea fatše, e tlosa ho lemoha ha lifaha tsa makenete, ho bonolo haholo ho tseba hore na moloko ho chip ke ofe.Ka lebaka la bothata ba BGA soldering, tjheseletsa pukwanana, haeba e se hlokolosi e tla ba haufi le phepelo ea motlakase le fatše libolo tse peli tsa solder short-circuited.
7. Nyenyane-boholo bo lekaneng tafole sticker capacitor tjheseletsa lokela ho ba hlokolosi, haholo-holo phepelo filtara capacitor (103 kapa 104), palo e khōlō, ho ke ke ho le bonolo ho etsa hore phepelo ea matla le fatše khutšoanyane.
