PCB qhia txog kev ua kom pom tseeb

PCB blanking, qhov thiab ua cov txheej txheem tuaj yeem txais txoj kev tuag blanking, rau kev ua PCB yooj yim lossis PCB nrog qhov tsis xav tau siab tuaj yeem siv txoj hauv kev khoob. Tsim nyog rau kev tsim khoom ntawm qib qis thiab ntau ntau PCB nrog qhov tsis xav tau siab thiab tsis xav tau lub cev zoo heev, nrog tus nqi qis.

Punch:

Kev tsim cov khoom loj, hom thiab tus naj npawb ntawm qhov thiab qhov nyuaj ntawm cov ntawv ib leeg ib sab thiab ob tog uas tsis yog xim hlau qhov epoxy iav daim ntaub substrate, feem ntau siv ib lossis ob peb tuag xuas nrig ntaus.

Cov duab ua:

Luam tawm pawg thawj coj saib ntau ntim ib lub vaj huam sib luag loj thiab ob chav vaj huam sib luag zoo, feem ntau yog tuag. Raws li qhov loj ntawm lub rooj tsav xwm luam tawm, nws tuaj yeem muab faib ua rau sab saud thiab ntog tuag.

Kev sib xyaw ua ke:

In order to shorten the manufacturing cycle and improve productivity, composite die is used to process the holes and shapes of single panel at the same time.

Txhawm rau txheej txheem luam ntawv nrog pwm, qhov tseem ceeb yog tsim thiab ua cov pwm, uas xav tau kev paub txuj ci txuj ci. Ib qho ntxiv, kev teeb tsa thiab debugging ntawm pwm kuj tseem ceeb heev. Tam sim no, feem ntau ntawm cov pwm ntawm PCB cov tuam txhab ua tiav los ntawm cov chaw tsim khoom sab nraud.

Ceev faj rau kev teeb tsa pwm:

1. Raws li kev tsim qauv suav ntawm qhov tsis muaj zog, qhov loj ntawm qhov tuag, kaw qhov siab ntawm kev xaiv nias (suav nrog hom, tonnage).

2. Start the punch, check the clutch, brake, slider and other parts are normal, the operating mechanism is reliable, there must be no continuous impact phenomenon.

3. The pad iron under the die, generally 2 pieces, must be ground on the grinder at the same time, to ensure that the die is installed parallel and vertical. Pad iron placement of the leap position that does not prevent material falling at the same time as close to the mold center.

4. Npaj ob peb txheej ntawm nias phaj thiab T-lub taub hau nias phaj screws rau kev sib txuam siv nrog pwm. Qhov kawg ntawm lub phaj xovxwm yuav tsum tsis txhob kov lub phab ntsa ncaj ntawm qhov tuag qis. Cov ntaub Emery yuav tsum tau muab tso nruab nrab ntawm cov chaw sib cuag thiab cov ntsia hlau yuav tsum tau nruj.

5. Thaum txhim kho cov pwm, xyuam xim rau cov ntsia hlau thiab cov txiv ntoo ntawm qhov qis tuag kom tsis txhob kov cov tuag sab saud (lub hauv paus tuag poob thiab kaw).

6. Thaum kho cov pwm, sim siv phau ntawv ntau dua li lub cav.

7. Txhawm rau txhim kho qhov ua tau zoo ntawm cov substrate, daim ntawv substrate yuav tsum tau rhaub. Nws qhov kub txog 70 ~ 90 ℃ yog qhov zoo tshaj plaws.

Lub qhov thiab cov duab ntawm cov tuag blanking luam ntawv board muaj cov hauv qab no tsis xws luag:

Raised ib ncig ntawm lub qhov los yog cov ntawv ci tooj liab warped los yog txheej; Muaj qhov tawg ntawm qhov; Qhov chaw sib txawv lossis qhov nws tus kheej tsis yog ntsug; Burr; Ntu ntxhib; Cov ntawv luam tawm tau ua rau hauv qab ntawm lub lauj kaub; Seem dhia dhia; Nkim jam.

Cov kev tshuaj xyuas thiab tshuaj xyuas yog raws li hauv qab no:

Txheeb xyuas seb qhov xuas nrig ntaus quab yuam thiab nruj ntawm qhov xuas nrig ntaus puas txaus; Tuag tsim yog tsim nyog, txhav txaus; Convex, concave tuag thiab qhia kab, qhia lub tes tsho machining raug yog tiav, kev teeb tsa yog concentric, ntsug. Txawm hais tias qhov kev tshem tawm haum yog txawm. Qhov sib txawv nruab nrab ntawm convex thiab concave yog me me lossis loj dhau los ua qhov tsis xws luag, uas yog qhov teeb meem tseem ceeb tshaj plaws hauv kev tsim pwm, ua tiav, debugging thiab siv. Lub ntsej muag thiab lub ntsej muag lub ntsej muag tsis raug tso cai kom muab sib npaug thiab sib dhos. Punch tsis raug tso cai kom muaj taper, tshwj xeeb tshaj yog thaum xuas nrig ob lub cev ib txwm thiab inverted cones tsis raug tso cai. Hauv kev tsim khoom, peb yuav tsum ua tib zoo saib xyuas seb lub ntug ntawm convex thiab concave tuag tau hnav. Lub qhov ncauj tawm yog qhov tsim nyog, tiv taus me me. Push the material board, the material rod is reasonable, enough force. Cov tuab ntawm cov phaj thiab cov quab yuam ntawm cov substrate, cov kua nplaum, thiab cov quab yuam ntawm tooj liab ntawv ci, cua sov thiab av noo thiab lub sijhawm tseem yog qhov tseem ceeb uas yuav tau txiav txim siab hauv kev tshuaj xyuas qhov tsis zoo.
