SMT chip processing ili ndi zida zofunikira zothandizira, ndiye phala la solder.
Solder phala zikuchokera makamaka malata ufa aloyi particles ndi flux (flux lili rosin, yogwira wothandizila, zosungunulira, thickener, etc.), solder phala ndi ofanana ndi otsukira mano, ntchito solder phala kusindikiza makina solder phala mu pcb PAD malo, kuti makina makina phiri zomata zigawo zamagetsi, ndiyeno kuti reflow soldering mkulu kutentha otentha Sungunulani solder phala ndiyeno anakonza zigawo zikuluzikulu pakompyuta kuti PAD.
Solder phala chifukwa chiyani kubwerera kutentha woyambitsa?
1. Chifukwa chiyani phala la solder liyenera kutenthedwa?
Solder phala zambiri kusungidwa mu firiji (5-10 madigiri Celsius) chilengedwe, kuchokera firiji adzatengedwa SMT msonkhano chilengedwe kutentha kusagwirizana, ngati mwachindunji lotseguka ntchito, ndi kukhudzana kutentha kusagwirizana, pamwamba pa solder phala. adzatsatira nthunzi madzi, ngati reflow soldering kutentha kwambiri, angaoneke anaphulika malata, chifukwa mu zoipa mikanda malata.Choncho, solder phala kuchotsedwa mufiriji zambiri bwino kubwerera kutentha 2-4H.
2. Chifukwa chiyani phala la solder liyenera kugwedezeka?
Solder phala anaika mu firiji, chifukwa cha zigawo zosiyanasiyana za solder phala, anaika kwa nthawi yaitali, zigawo zosiyanasiyana za solder phala adzaoneka wosanjikiza chodabwitsa, kotero muyenera kusonkhezera (kuyambitsa mu njira yomweyo 20-30 kutembenuka. akhoza kukhala), ngati si anasonkhezeredwa mwachindunji ndi, ndiye zigawo zosiyanasiyana za solder phala si osakanikirana, sangathe kusewera ntchito solder phala palokha.
Chifukwa chomwe phala la solder liyenera kusungidwa mufiriji m'malo molunjika pamalowa ndikuti phala la solder lili ndi zosungunulira ndi rosin, zomwe zimatuluka nthunzi ngati zitayikidwa mwachindunji pamalo abwino, motero zimapangitsa kuti mpweya uume.
Pali zodziwikiratu solder phala kasamalidwe makabati pa msika, kuphatikizapo yosungirako, tempering ndi basi yogwira mtima, etc. Ngati kampani yaikulu ndi ntchito zambiri solder phala, mukhoza kugula zipangizo zimenezi kusamalira ndi ntchito solder phala.

Kusintha kokhazikika
1. Dongosolo Lolondola la Optical Positioning System
Njira zinayi zosinthira kuwala, kulimba kwa kuwala kumasinthika, kuwala kumakhala kofanana, ndipo kupeza zithunzi ndikwabwino kwambiri.
2. Kuchita bwino kwambiri komanso kusinthasintha kwakukulu kwa stencil kuyeretsa dongosolo
mbale yofewa yosamva mphira yopukutira, njira zoyeretsera zowuma, zonyowa komanso zovundikira
kuyeretsa bwino, disassembly yabwino.
3. Wanzeru squeegee dongosolo
Kukonzekera kwanzeru, ma motors awiri odziyimira pawokha omwe amayendetsedwa ndi squeegee, omangidwa mu dongosolo lowongolera bwino lomwe.
4. Special PCB makulidwe zosinthika dongosolo
Kutalika kwa nsanja kumangoyesedwa molingana ndi mawonekedwe a PCB makulidwe, omwe ndi anzeru, othamanga, osavuta komanso odalirika pamapangidwe.
5. Solder Paste Printing Quality Kuyanika
Ntchito ya 2D imatha kuzindikira mwachangu zolakwika zosindikiza, malo ozindikira amatha kuwonjezedwa mosasamala.
6. Kusindikiza axis Servo Drive
Sinthani kalasi yolondola, perekani nsanja yabwino yosindikizira, kukhazikika kwa magwiridwe antchito, kukulitsa moyo wautumiki.
