Hauv kev tsim khoom ib puag ncig-los ntawm kev kub ntxhov ntawm SMT reflow soldering mus rau cov tshuaj hnyav hnyav ntawm PCB los ua ke- cov ntawv txheem tsuas yog ua tsis tau. Lawv tev, tshem tawm xim, los yog tig mus rau cov tshauv, ua rau poob traceability, kim rework, thiab ua raws li mob taub hau. Qhov no yog qhov siab - kub PI daim ntawv lo los ua si.
Dab tsi yog High -Temperature PI Label?
Txhais Polyimide (PI) Label Khoom
Lub siab - qhov kub thiab txias PI daim ntawv lo yog ib qho tshwj xeeb ntawm tus kheej - nplaum nplaum tsim los ntawm polyimide zaj duab xis - siab - ua tau zoo polymer renowned rau tshwj xeeb thermal stability, tshuaj tiv thaiv, thiab mechanical toughness. Feem ntau raug xa mus rau hauv kev lag luam los ntawm nws lub npe nrov tshaj plaws, "Kapton®," polyimide ua cov khoom siv zoo tshaj plaws rau cov ntawv sau uas yuav tsum muaj sia nyob rau cov txheej txheem kev lag luam ntau tshaj plaws.
PI vs. PET vs. Standard Paper: Kev sib piv ceev
Tsis yog tag nrho cov siab - cov ntawv ntsuas kub yog tsim sib npaug. Thaum cov ntawv polyester (PET) tuav cov cua kub nruab nrab txog li 150 degree, lawv degrade nyob rau hauv lub sij hawm raug rau huab cua kub heev. Polyimide, los ntawm qhov sib txawv, muab kev ua haujlwm tsis sib xws:
- Polyimide (PI): Nrog rau 260℃-400℃+; superior tshuaj thiab abrasion kuj; UL- tau lees paub.
- Polyester (PET): Zoo rau 150℃ntau yam; tsim nyog rau kev siv dav dav, tab sis ua tsis tiav nyob rau hauv yoj soldering.
- Ntawv / Txheem Synthetics: qis tshaj qhov cua sov; tsis haum tshaj 100 degree; Feem ntau tsis siv hauv SMT ib puag ncig
Rau cov ntawv thov uas yuav tsum tau ua kom raug coj mus rau - dawb soldering peaks lossis aggressive wash chemistry, PI tseem yog tus qauv kev lag luam uas tsis muaj teeb meem.
Cov yam ntxwv tseem ceeb ntawm High -Tub kub PI Labels
Exceptional Thermal Endurance
Lub ntsiab yam ntxwv ntawm daim ntawv lo polyimide yog nws txawv tshaj plaw tshav kub. Nyob ntawm qib thiab cov nplaum nplaum, PI cov ntawv tseem muaj sia nyob qhov kub thiab txias ntawm -70℃txog 280 degree, nrog rau lub sijhawm luv luv mus txog 320℃-400℃thaum cov txheej txheem xws li yoj soldering. Ntau cov khoom lag luam uas tau lees paub UL tuaj yeem tiv thaiv ntau yam rov qab thiab yoj lub voj voog uas tsis muaj delamination, blistering, lossis discoloration.
- Chemical & Solvent Resistance
Lub tshav kub- daim ntawv lo tiv thaiv tsuas yog siv tau raws li nws lub peev xwm los tawm tsam tshuaj lom neeg. Cov ntawv PI sawv ntsug rau cov dej ntws tawm, cov tshuaj ntxuav tu (xws li ZESTRON VIGON), isopropyl cawv, roj, muaj zog acids thiab alkalis, thiab ntau cov kuab tshuaj. Cov tshuaj tiv thaiv zoo li no ua rau lawv tsis muaj nuj nqis hauv PCB los ua ke, automotive nyob rau hauv - hood applications, thiab electronics manufacturing.
- Mechanical Strength & Abrasion Resistance
Tshaj li cua sov thiab tshuaj lom neeg, cov ntawv sau ua lag luam ntsib cov neeg siv khoom siv los ntawm kev tuav, kev thauj mus los hauv pawg thawj coj saib, thiab cov khoom siv tuaj tos. Polyimide films muaj lub zog tensile siab (kwv yees li 200 MPa ntawm chav tsev kub) thiab elongation zog uas tiv thaiv tearing, abrasion, thiab nto scuffing, kom ntseeg tau tias barcode kev ncaj ncees tseem nyob twj ywm los ntawm kev soj ntsuam zaum kawg.
- Thermal Transfer Printability & High-Resolution Imaging
Txhawm rau pab kom traceability, ib daim ntawv lo yuav tsum nqa cov ntaub ntawv zoo, scannable. PI cov ntawv sau ua haujlwm zoo tshaj plaws rau kev luam ntawv thermal hloov pauv, ua kom cov kab ntawv ci ntsa iab, QR cov lej, cov ntaub ntawv lej lej, thiab cov ntawv sau lej ntawm kev daws teeb meem txog 600 dpi. Cov coatings no kuj muab opacity, hloov lub ntuj amber polyimide mus rau hauv ib tug kaj dawb keeb kwm yav dhau rau siab - sib piv imaging.
