Q2: Dab tsi yog qhov zoo ntawm koj lub tuam txhab kev pabcuam OEM?
A2:Peb cov khoom siv tau maj mam txo qis thiab peb qhov project tau ua kom zoo dua.
Tuam txhab paub
PCB saj zawg zog Circuit Court board vuam txoj kev lag luam
1. Ua ntej soldering, siv flux rau ntawm lub ncoo thiab kho nws nrog ib tug soldering hlau kom tsis txhob pluag tin plating los yog oxidation ntawm lub ncoo, ua rau tsis zoo soldering, thiab nti feem ntau tsis tas yuav tsum tau ua.
2. Ua tib zoo tso PQFP nti rau ntawm PCB nrog tweezers, saib xyuas kom tsis txhob ua kom cov pins puas. Teem nws nrog cov ntaub qhwv, xyuas kom tseeb tias cov nti tau muab tso rau hauv qhov kev taw qhia kom raug. Kho qhov kub ntawm cov hlau soldering mus rau ntau tshaj 300 degrees Celsius, poob ib tug me me ntawm solder ntawm lub ntsis ntawm lub soldering hlau, nias rau ntawm lub nti uas tau ua raws li cov cuab yeej, thiab ntxiv ib tug me me flux mus rau lub soldering hlau. pins ntawm ob lub ces kaum opposite. Tuav lub nti thiab solder tus pins ntawm ob lub kaum sab nraud kom lub nti ruaj khov thiab tsis tuaj yeem txav mus los. Rov xyuas qhov sib dhos ntawm cov nti tom qab soldering cov kab kab pheeb ces kaum. Kho yog tias tsim nyog lossis tshem tawm thiab rov kho dua ntawm PCB.
3. Thaum pib solder tag nrho cov pins, ntxiv solder rau lub ntsis ntawm cov hlau soldering thiab siv flux rau tag nrho cov pins kom cov pins ntub. Kov qhov kawg ntawm txhua tus pin ntawm cov nti nrog lub ntsis ntawm cov hlau soldering kom txog thaum koj pom cov hlau ntws mus rau hauv tus pin. Thaum soldering, tuav lub taub ntawm cov hlau sib txuas mus rau cov pins kom tau soldered los tiv thaiv kev sib tshooj vim yog cov khoom siv ntau dhau.
4. Tom qab soldering tag nrho cov pins, ntub tag nrho cov pins nrog flux los ntxuav lub solder. Absorb tshaj solder qhov xav tau los tshem tawm cov luv thiab laps. Thaum kawg, siv tweezers los xyuas seb puas muaj ib qho kev sib tw virtual. Tom qab kev soj ntsuam tiav lawm, tshem tawm cov flux los ntawm lub rooj tsav xwm hauv Circuit Court, dipped ib tug txhav txhuam hauv cawv thiab so kom zoo raws li cov kev taw qhia ntawm cov pins kom txog thaum cov flux ploj mus.
