Dab tsi yog qhov tseem ceeb ntawm FPC fake stickers, kub nias thiab tshuaj ntsuam luam ntawv txheej txheem

Fake post

Fake nplaum tiv thaiv zaj duab xis, muaj zog board thiab rov qab kua nplaum; Cov yeeb yaj kiab tiv thaiv feem ntau muaj cov haujlwm ntawm insulating, tiv thaiv Circuit Court tiv thaiv soldering, thiab ua kom yooj yim ntawm cov khoom muag; lub rooj tsavxwm muaj zog yog tsuas yog los txhim kho cov neeg kho tshuab lub zog thiab coj cov kev nkag ntawm FPC davhlau ya nyob twg Lub luag hauj lwm ntawm lub connector; cov nplaum feem ntau plays lub luag haujlwm ntawm kev kho.

Cov txheej txheem ua haujlwm:

1. Npaj cov cuab yeej, txiav txim siab tus naj npawb ntawm cov khoom lag luam ib nrab yuav tsum tau faked, thiab npaj cov khoom tiag coverlay semi-tiav lawm.

2. Tshem tawm daim ntawv tso tawm ntawm Coverlay.

3. Cov ntawv ci tooj liab yuav tsum tsis txhob oxidized. Tshawb xyuas thiab ntxuav cov ntawv ci tooj liab: txhuam lub ntsej muag maj mam nrog txhuam kom tshem tawm dander lossis impurities.

4. Teem lub coverlay kom raug raws li cov lus qhia ua hauj lwm thiab coverlay kom raug raws li cov lus qhia ua hauj lwm thiab txoj hauj lwm thiab cov kev cai ntawm daim ntawv ntsuam xyuas tus qauv, thiab kho nws nrog ib tug hluav taws xob hlau.

5. Cov khoom lag luam ib nrab tiav tom qab muab tshuaj cuav yuav tsum raug xa mus rau qhov chaw nres tsheb kub kub sai li sai tau

ua tau kom tsis txhob oxidation. Kev tswj xyuas kom pom tseeb:

1. Nws yuav tsum tau hais tias daim ntawv qhia kev ua hauj lwm thiab kev soj ntsuam tus qauv daim card lub cev tswj coverlay raug thiab drilling txoj hauj lwm yog kiag li lawm.

2. Qhov tseeb offset ntawm coverlay kev sib raug zoo ntawm cov vuam thiab qhov hluav taws xob xaus yuav tsum tsis txhob tshaj qhov yuav tsum tau ntawm kev qhia ua hauj lwm thiab daim ntawv tshuaj ntsuam xyuas.

3. Cov neeg uas yuav tsum tau electroplated nrog tin los yog npib tsib xee-kub yuav tsum tawm ntawm plating tom, feem ntau 5cm.

4. Yuav tsum tsis muaj oxidation ntawm cov ntawv ci tooj liab, tsis muaj burrs ntawm cov npoo ntawm cov npog npog, thiab tsis muaj impurities nyob rau hauv coverlay.

5. Ua kev soj ntsuam zoo.

6. Tsis txhob muab cov cuab yeej ua haujlwm rau ntawm lub qhov ciaj ntswj, txwv tsis pub nws yuav ua rau khawb lossis tawg.

Kev kuaj pom pom:

1. Cov ntawv ci tooj liab tsis tuaj yeem oxidized.

2. Yuav tsum tsis muaj burrs ntawm cov npoo ntawm cov npog npog thiab ntawm cov npoo uas muaj zog.

3. Yuav tsum tsis muaj impurities nyob rau hauv coverlay thiab paving.

3. Yuav tsum tsis txhob muaj qhov paug ntawm paving.

4. Rau cov khoom siv los ntawm cov cav tov, nws yog ib qho tsim nyog yuav tsum tau xyuas kom tsis muaj cua npuas, tsis zoo, lossis kev sib xyaw ua ke.

Kub nias

Kev ua haujlwm kub kub muaj xws li ob peb kauj ruam xws li tsoos nias, txias nias, nrawm nrawm, thiab B-baking; Lub hom phiaj ntawm kev kub nias yog ua kom cov yeeb yaj kiab tiv thaiv los yog plywood ua raws li cov ciaj ntswj, uas tuaj yeem muab faib ua lub siab rhiab raws li nws txoj kev kho Adhesives thiab thermosetting adhesives tuaj yeem ua tiav zoo adhesion los ntawm kev tswj kub, siab, lamination lub sijhawm, stacking thiab ua ke ntawm cov khoom pab, thiab lwm yam, thiab txo qis kev raug mob siab, npuas, wrinkles, overflows hauv kev ua haujlwm. Rau qhov tsis xws luag xws li cov kua nplaum thiab cov hlau tawg, nws tuaj yeem muab faib ua ib leeg-sab nias txoj kev thiab ob-sided nias txoj kev raws li kev sib xyaw ntawm cov khoom pabcuam.

Ib, ceev nias:

1. Kev sib xyaw ua ke: kev nias ib zaug thiab ob sab nias, feem ntau yog siv ib sab nias.

2. Cov khoom siv pabcuam siv thiab lawv cov haujlwm

(1) Fiberglass daim ntaub: kev sib cais, tso tawm

(2) Neflon: tsis muaj plua plav, tiv thaiv kev raug mob

(3) Hlawv hlau phaj: cua sov, roj

2. Ib txwm muaj siab:

1. Kev sib xyaw ua ke: kev nias ib sab thiab ob sab nias

2. Cov khoom siv pabcuam siv tau zoo heev:

(1) Talc: txo qhov nplaum thiab tiv thaiv wrinkles

(2) TPX: kev sib cais, kev tiv thaiv plua plav, tiv thaiv impurity

(3) Cardboard: tsis muaj siab

(4) Aluminium alloy phaj: Flatness

3. Ua haujlwm tseem ceeb

Parameters: kub, siab, typeetting method, nias lub sij hawm plaub, feem ntau faults thiab tsis tshua muaj tshwm sim ua rau:

1. Npuas:

(1) Cov khoom siv xws li silicone film thiab cardboard yog siv tsis tau

(2) steel phaj tsis tiaj tus

(3) Cov yeeb yaj kiab tiv thaiv tau tas sijhawm

(4) Qhov kev teeb tsa tsis raug, xws li lub siab siab dhau lawm thiab lub sijhawm preloading luv dhau.

(5) Kev teeb tsa tsis raug

2. Crushing:

(1) Cov khoom siv pabcuam tsis huv

(2) TPX kev tso kawm teeb meem

(3) Qhov chaw ntawm iav fiber ntau daim ntaub

3. Txhim kho cov phaj hloov

(1) Instantaneous siab loj heev

(2) Lub zog yog tuab heev

(3) Txhim kho cov ntawv nplaum cuav tsis muaj zog (kev sib tsoo zoo tsis zoo)

4. Glue overflow:

(1) Adhesive tsis txaus ntawm cov ntaub ntawv pabcuam

(3) Cov yeeb yaj kiab tiv thaiv muaj burrs loj

(4) Cov kev txwv thiab lawv qhov teeb tsa tsis raug, piv txwv li, lub siab ceev yog qhov loj heev.

5. Tag nrho cov suab tsis zoo:

(1) Txoj kev nias tsis raug

(2) Kev suav ntawm tus nqi shrinkage tsis raug. 5. Kev lees paub zoo:

1. Tom qab nias, nws yuav tsum tiaj tus, thiab yuav tsum tsis muaj wrinkles, kev raug mob siab, huab cua npuas, curling thiab lwm yam tshwm sim.

2. Cov kab yuav tsum tsis txhob rub thiab tawg vim muaj kev cuam tshuam ntawm kev nias.

3. Cov Coverlay lossis cov plywood yuav tsum tau muab kaw kom tiav, thiab nws yuav tsum tsis txhob tev tawm thaum tev tawm ntawm tes.

Screen luam ntawv

1.Lub hauv paus ntsiab lus ntawm kev tshuaj ntsuam luam ntawv:

Siv polyester lossis stainless hlau mesh ua tus nqa khoom, cov qauv ntawm cov yeeb yaj kiab zoo thiab tsis zoo raug xa mus rau cov mesh hauv cov latex ncaj qha los yog cov phaj tsis ncaj los ua ib lub mesh, uas yog siv los ua ib qho cuab yeej rau kev luam ntawv ntawm sab nraud.

2. Kev faib cov inks siv hauv kev luam ntawv thiab lawv cov haujlwm:

Solder mask number case---- rwb thaiv tsev, tiv thaiv Circuit Court

Text-------kos kab cim, thiab lwm yam.

Silver paste------- tiv thaiv hluav taws xob cuam tshuam

Peeled kua nplaum ------ anti-plating

Acid resistance-------- filling, corrosion inhibitor

3. kev pom zoo

1. Txoj hauj lwm thiab kev taw qhia ntawm kev luam ntawv yuav tsum ua raws li cov khoom siv tiag tiag ntawm kev qhia ua haujlwm thiab daim ntawv tshuaj ntsuam xyuas.

2. Yuav tsum tsis muaj kiv taub hau, ruaj khov, los yog pinholes.

3. Feem ntau, lub cim overprint yuav tsum ua raws li ntxiv rau 0.5mm/-0.5mm. Yog tias muaj cov kev cai tshwj xeeb ntawm kev tshuaj ntsuam luam ntawv ntawm cov ntawv qhia ua haujlwm thiab daim ntawv tshuaj ntsuam xyuas, nws yog qhov zoo dua.

4. Tom qab xa cov cua sov kom qhuav, nws yuav tsum tau kuaj nrog 3M daim kab xev, thiab yuav tsum tsis txhob muaj tus number case poob.

Lus Cim: Qhov ntsuas kub ntawm qhov kev xa khoom kub kub yuav tsum tsim nyog kom tsis txhob yaj ntawm cov tin thiab txhuas ntawm qee qhov ci tin thiab txhuas cov khoom semi-tiav.

SMT

Txoj ntsiab cai nkag siab:

SMT yog nto mount technology, uas yog ib tug txheej txheem ntawm tiaj vuam qhov chaw nyob rau saum npoo ntawm lub Circuit Court board, thiaj li hais tias cov ntaub qhwv nyob rau hauv lub board nto thiab qhov kawg ntawm cov khoom yog ua ke nrog solder. Cov xwm txheej tseem ceeb rau kev vuam zoo: a. Txhawm rau kom muaj kev sib raug zoo ntawm cov hlau nto thiab cov kev sib raug zoo yuav tsum tau ua kom zoo vuam

b. Xaiv cov flux tsim nyog

c. Qhov tseeb solder alloy muaj pes tsawg leeg

d. Txaus cua sov thiab haum cua sov nkhaus. Common adverse phenomena:

1.conn: Cov khoom yog deformed, ob txhais taw yog crooked, thiab solder tiv thaiv crawls deb.

2.FPC: Npuas, crush, wrinkle, luam txheej txheej, mis-soldered qhov chaw.

3. Soldering pads: luv Circuit Court, cua soldering, txias soldering, tin penetration, tin taub hau, tin ntau, qhwv soldering, sib cais

4.lwm yam: tin hlaws, tin slag, nplaum nplaum tiv taus, crumb residue.
