Yuav ua li cas rau Solder Flex Pcb

Cov kauj ruam ua haujlwm yooj yim Circuit Board

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. Siv cov tweezers ua tib zoo tso PQFP nti ntawm PCB, 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. Yuav pib soldering tag nrho cov pins, ntxiv solder rau lub ntsis ntawm lub soldering hlau 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 leads, ntub tag nrho cov leads 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.

5. SMD RC Cheebtsam yog qhov yooj yim rau solder. Koj tuaj yeem muab cov tin rau ntawm ib qho kev sib koom ua ntej, tom qab ntawd muab ib qho kawg ntawm cov khoom siv, clamp cov khoom siv nrog tweezers, thiab solder ib kawg, thiab tom qab ntawd xyuas seb nws puas muab tso rau kom raug; Yog hais tias nws yog ncaj, ces solder rau lwm kawg.

Flexible circuit board soldering ceev faj

Nyob rau hauv cov nqe lus ntawm layout, thaum qhov loj ntawm lub rooj tsavxwm Circuit Court yog loj heev, txawm hais tias lub soldering yog yooj yim rau kev tswj, cov ntawv luam tawm cov kab ntev, impedance nce, lub peev xwm los tiv thaiv lub suab nrov txo, thiab tus nqi nce; Yog hais tias nws yog me me, lub tshav kub dissipation txo, lub soldering yog ib qho nyuaj rau tswj, thiab cov kab uas nyob ib sab yog nquag tshwm sim. Kev sib cuam tshuam, xws li electromagnetic cuam tshuam ntawm Circuit Court boards, thiab lwm yam. Yog li ntawd, PCB board tsim yuav tsum optimized:

(1) Txo qhov kev sib txuas ntawm cov khoom siv ntau zaus thiab txo EMI cuam tshuam.

(2) Cov khoom uas hnyav hnyav (xws li ntau tshaj 20g) yuav tsum tau kho nrog cov hlua khi thiab tom qab ntawd welded.

(3) Qhov teeb meem ntawm cov cua kub dissipation yuav tsum raug txiav txim siab rau cov khoom cua sov kom tsis txhob muaj qhov tsis xws luag thiab rov ua haujlwm los ntawm qhov loj ΔT nyob rau saum npoo ntawm cov khoom, thiab cov khoom siv thermal yuav tsum tau khaws cia kom deb ntawm qhov cua sov.

(4) Cov txheej txheem ntawm cov khoom yuav tsum tau ua tib zoo sib xws, uas tsis yog tsuas yog zoo nkauj xwb tab sis kuj yooj yim rau welding, thiab yuav tsum tau tsim ntau. Lub rooj tsavxwm tsim yog 4: 3 duab plaub (zoo tshaj). Tsis txhob hloov lub dav hlau sai sai kom tsis txhob muaj kev cuam tshuam ntawm kev sib txuas. Thaum lub Circuit Court board yog rhuab mus ntev, cov ntawv ci tooj liab yog ib qho yooj yim kom nthuav thiab poob tawm. Yog li ntawd, yuav tsum tsis txhob siv cov ntawv loj loj ntawm cov ntawv ci. Cov saum toj no yog cov vuam ntawm lub rooj tsavxwm hloov tau yooj yim, kuv vam tias nws tuaj yeem pab koj.
