Tsis siv neeg suav muaj nuj nqi ntawm lub sij hawm luam ntawv

Scrapers

Zoo ib yam li tag nrho cov tshuab luam ntawv tsis siv neeg, lub scraper tuaj yeem txav mus los thiab nqis

Lub siab ntawm scarpering yog adjustable raws li ib tug txawv qauv ntawm lub scraper.

Lub sijhawm nres ntawm scraper ntawm txoj haujlwm ntawm sab laug / sab xis thiab sab laug / sab xis tuaj yeem teeb tsa ntawm nws tus kheej

Qhov ceev ntawm cov scrapers tuaj yeem hloov kho

Thaum muaj xwm ceev nres ntawm cov scrapers kom muaj kev nyab xeeb.

Stencil

Zoo ib yam li lub tshuab luam ntawv tsis siv neeg puv, stencil yuav nce qeeb hauv 2 vib nas this rau demould

tom qab ntawd sai sai kom tawm ntawm PCB, uas tsis txhob cuam tshuam cov xaim teeb duab tshwm sim hauv demould

thiab txuag lub sijhawm thiab txhim kho kev tsim khoom.

Kev Tswj Xyuas Zoo

Peb muaj QC tus neeg nyob hauv cov kab ntau lawm ua rau kev tshuaj xyuas.

Tag nrho cov khoom yuav tsum tau kuaj xyuas ua ntej xa khoom. Peb ua inline soj ntsuam thiab zaum kawg soj ntsuam.

1. Tag nrho cov khoom siv raw tau kuaj xyuas thaum nws tuaj txog peb lub Hoobkas.

2. Txhua daim thiab lub logo thiab tag nrho cov ntsiab lus tshawb xyuas thaum lub sijhawm tsim khoom.

3. Tag nrho cov ntsiab lus ntim tau kuaj xyuas thaum lub sijhawm tsim khoom.

4. Tag nrho cov khoom tsim tau zoo thiab ntim tau kuaj xyuas qhov kawg tom qab ua tiav.

Yog hais tias ib qho PCB los ua ke cov kab ntau lawm yuav tsum tau, SMT PCB tshuab luam ntawv Semi- pib lub tshuab luam ntawv solder + khaws thiab tso tshuab + smt conveyor + reflow soldering cub tuaj yeem muab.

FAQ

Q1. Dab tsi ua rau solder paste sticking rau stencil apertures?

• Aperture tsim:Tapered phab ntsa (xws li laser- txiav stencils) txo adhesion.
• Paste zoo:Siv hom 3/4 pastes nrog viscosity kom zoo (piv txwv li, 800–1,200 kcps).
• Ib puag ncig:Tswj cov av noo ntawm 40-60% RH kom tsis txhob muab tshuaj txhuam kom qhuav.

Q2. Kuv yuav ua li cas kom ntev lub squeegee hniav lifespan?

• Khoom siv:Siv polyurethane hniav (60-80 Shore hardness) rau durability.
• Kev sib hloov:Hloov cov hniav txhua 4-8 teev kom faib cov khaub ncaws sib npaug.
• Cia:Khaws cov hniav nyob rau hauv qhov chaw tsaus, qhuav kom tiv thaiv UV / av noo degradation.

Q3. Yuav ua li cas optimize solder paste tso tawm los ntawm stencil apertures?

• Xyuas kom cov stencil thickness sib phim cov khoom siv suab (xws li, 0.1mm rau 0201 Cheebtsam)
• Tswj kom zoo aperture phab ntsa geometry (laser- txiav + electro- polished pom zoo)
• Tswj kev luam ntawv ib puag ncig ntawm 25 ± 2℃/ 50 ± 10% RH
• Siv hom 3 lossis 4 solder paste nrog 90-95% cov ntsiab lus hlau

Q4. Dab tsi ua rau kev luam ntawv tsis zoo (smearing / hla)?

• Tsis txaus squeegee siab (hloov mus rau 4-6kg quab yuam)
• Hnav squeegee hniav (hloov txhua 50,000-80,000 luam tawm)
• stencil tsis raug -PCB sib cais ceev (0.1-0.5mm/sec)
• Kab mob stencil underside (huv txhua 10-15 luam)
   

Q5. Vim li cas cov tshuaj pleev xim qhov siab sib txawv ntawm PCB?

• Uneven stencil tension (should be >35 N / cm²)
• PCB txhawb tus pins tsis raug tso cai (siv 1 tus pin ib 100cm²)
• Squeegee hniav lub kaum sab xis sib txawv (tso 60 ± 5 degree)
• Solder paste slump (kub paste kub<26°C)
