I. Stencil tshuab luam ntawv hom
1. Phau ntawv Stencil tshuab luam ntawv
Lub tshuab luam ntawv phau ntawv yog qhov yooj yim tshaj plaws thiab pheej yig tshaj luam ntawv tshuab.PCB tso thiab tshem tawm yog ua tiav manually, lub squeegee yuav siv tau los ntawm tes los yog txuas nrog lub tshuab, thiab luam ntawv txiav txim yog ua manually.PCB thiab steel phaj parallelism sib dhos los yog ntug ntawm lub rooj tsavxwm kom ntseeg tau tias txoj haujlwm yog nyob ntawm tus neeg teb xov tooj cov kev txawj ntse, yog li txhua tus luam ntawv PCB, cov ntawv luam ntawv yuav tsum tau hloov kho thiab hloov.
2. Semi-automatic tshuab luam ntawv
Semi-automatic presses yog tam sim no cov khoom siv dav siv ntau tshaj plaws, lawv yeej zoo ib yam li phau ntawv xovxwm, qhov kev tso kawm thiab tshem tawm ntawm PCBs tseem cia siab rau kev siv phau ntawv, qhov sib txawv tseem ceeb ntawm phau ntawv tshuab yog kev txhim kho lub taub hau luam ntawv, lawv tuaj yeem tswj tau zoo dua ntawm kev luam ntawv ceev, squeegee siab, squeegee lub kaum ntse ntse, luam ntawv nrug thiab tsis sib cuag, cov cuab yeej lub qhov lossis PCB npoo tseem siv tau los ua haujlwm, thaum lub phaj steel los pab cov neeg ua haujlwm zoo ua tiav ntawm PCB thiab steel phaj parallelism hloov. .
3. Tsis siv neeg puv tshuab luam ntawv
Cov nplaum nplaum yog luam tawm ntawm cov ntaub qhwv ntawm cov khoom ntawm lub hauv paus board, tab sis tam sim no qhov loj ntawm cov khoom siv saum npoo av tau txais me dua thiab zoo dua, yog li kev tsim ntawm lub hauv paus pawg thawj coj saib me me thiab zoo dua.Yog li ntawd, qhov tseeb thiab kev ua haujlwm ntawm solder paste luam ntawv yuav tsum tau txhim kho zoo heev.Niaj hnub no, feem ntau ntawm cov khoom siv hluav taws xob siv hluav taws xob siv hluav taws xob tsis siv neeg lossis tag nrho automated solder paste tshuab luam ntawv los tsim cov khoom lag luam SMT, thiab kev tso tawm PCB yog ua los ntawm ntug-bearing conveyor siv, nrog cov txheej txheem tsis xws li squeegee ceev, squeegee siab, luam ntawv ntev, thiab non-contact pitch tag nrho cov programmable.
PCB qhov chaw yog ua tiav los ntawm kev siv qhov chaw los yog cov npoo ntawm lub rooj tsavxwm, thiab qee cov khoom siv txawm tuaj yeem siv lub tshuab tsis pom kev los ua kom cov PCB thiab steel phaj sib npaug rau ib leeg, uas tshem tawm qhov yuam kev los ntawm ntug qhov chaw thaum siv cov tshuab tsis pom kev, thiab ua rau qhov chaw yooj yim, nrog phau ntawv qhia kev pom zoo hloov los ntawm lub zeem muag.Cov tshuab luam ntawv luam tawm tshiab tshiab tau nruab nrog lub ntsej muag yees duab los saib xyuas qhov xwm txheej luam ntawv thiab kho txhua lub sijhawm.
II.Stencil tshuab luam ntawv tu
Tshem tawm cov squeegee, siv daim ntawv tshwj xeeb dipped nyob rau hauv anhydrous ethanol, so lub squeegee huv si, thiab ces ntsia rau hauv lub taub hau luam ntawv los yog tau txais nyob rau hauv lub cuab yeej txee.
Ntxuav cov stencil, muaj ob txoj hauv kev.
Txoj Kev 1: Kev ntxuav lub tshuab ntxhua khaub ncaws.Ntxuav cov cuab yeej nrog cov qauv, cov nyhuv tu yog qhov zoo tshaj plaws.
Txoj Kev 2:Kev ntxuav tes.
Siv daim ntawv so tshwj xeeb los siv cov tshuaj ethanol, cov tshuaj txhuam hniav yuav raug tshem tawm, yog tias cov dej xau qhov thaiv, muaj cov txhuam hniav mos, tsis txhob stab nrog rab koob tawv.
Siv cov phom cua compressed los tshuab cov seem nyob rau hauv lub qhov to ntawm lub template kom huv si.
Muab cov qauv tso rau ntawm lub tshuab ua haujlwm muab tshuaj, txwv tsis pub txais nws hauv lub cuab yeej txee.
