PTFE High-temperature Daim kab xev rau FPC Kub Xovxwm Lamination Defect Tiv Thaiv

Raws li cov kws tshaj lij kev lag luam ntawm PTFE daim kab xev kub kub, Jiangsu Aokai Cov Khoom Tshiab muab cov lus qhia ntxaws ntxaws rau koj. Nyob rau hauv cov txheej txheem kub xovxwm lamination ntawm Flexible Printed Circuit Boards (FPC), PTFE high-temperature daim kab xev hais txog ob qho tseem ceeb tsis xws luag - substrate wrinkling thiab adhesive hloov - los ntawm kev sib xyaw ua ke ntawm cov khoom siv hauv lub cev (tsis tshua muaj zog saum npoo, siab seem stability) thiab optimized processing technologies (stacking structure design, parameter control). Nws ua hauj lwm raws li ib tug zoo tagnrho huv kev cais txheej  thiab siab equalizing tsis txheej.

I. Ua rau Substrate Wrinkling thiab Adhesive Transfer

Substrate Wrinkling Lub hauv paus ua rau nyob rau hauv tsis sib xws thaum tshav kub kub thiab siab tis. FPC yog tsim los ntawm ntau yam ntaub ntawv xws li PI zaj duab xis, tooj liab ntawv ci thiab adhesives nrog sib txawv coefficients ntawm thermal expansion (CTE). Tsis tas li ntawd, Circuit Board tsim yam tseem ceeb nrog rau qhov tsis sib xws ntawm tooj liab thickness thiab stiffener cov kauj ruam yuav ua rau tsis sib xws ntawm kev faib tawm. Cov cua kub tsis sib xws thiab siab ua rau cov khoom siv sab hauv kev ntxhov siab, ua rau wrinkling, warping thiab delamination.

Adhesive Transfer (Residual Adhesive) Qhov no feem ntau yog tshwm sim los ntawm kev sib tshuam thiab cov khoom tsis xws luag. Cov nplaum nplaum semi-kho ntawm npog zaj duab xis rau lamination melts thiab ntws hauv qhov kub thiab txias, thiab adheres rau saum npoo ntawm cov khoom sib cais. Lub caij no, yog tias lub silicone siab-rhiab nplaum nplaum coated nyob rau sab nraum qab ntawm PTFE daim kab xev muaj qhov kub tsis txaus los yog cov txheej txheem tsis sib haum, cohesive tsis ua hauj lwm yuav tshwm sim ntawm qhov kub thiab txias, ua rau ib nrab nplaum hloov mus rau FPC nto.

II. Core Mechanisms ntawm PTFE High Temperature Daim kab xev rau kev tiv thaiv tsis xws luag

Kev tiv thaiv ntawm substrate Wrinkling

Thermal shock rho tawm & tsis tu ncua siab tis nyob rau hauv tus txheej txheem stacking qauv: Kub phaj → PTFE daim kab xev → silicone cushion → FPC → PTFE daim kab xev → Kub phaj , PTFE daim kab xev ua raws li ib tug tso txheej. Nws ruaj khov thermal conductivity ua kom muaj kev sib hloov ntawm cov cua sov. Kev koom tes nrog silicone buffer cushions, nws txo cov kev ntxhov siab los ntawm qhov sib txawv thermal expansion thiab sib npaug tag nrho cov siab, zam kev ntxhov siab hauv zos thiab tom qab wrinkling. Rau high-precision ntau lawm, iav-fiber reinforced PTFE daim kab xev nrog tsawg CTE yog pom zoo rau superior seem stability.

Ruaj khov thermal ua qhov rais Lub PTFE txheej thaiv ncaj qha thermal cuam tshuam. Ua ke nrog cov thermal hysteresis ntawm silicone cushions, tshav kub conduction yuav maj mam thiab ruaj khov. Nws tswj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm ≤ 5 ~ 7 ℃ thaum lub sij hawm nplaum gelling, ua kom tiav cov pa tawm ua ntej cov nplaum nplaum ruaj khov, thiab tshem tawm cov qhov txhab los ntawm qhov ntxov ntxov gelling thiab qeeb tso pa tawm. Cov cua kub ntawm qhov ntsuas kub tseem ceeb tau pom zoo kom tswj tau ntawm 4.5 ~ 5.0 ℃ / min.

Tshem tawm ntawm Adhesive Transfer

Cov cuab yeej uas tsis yog lo nrog ultra-low nto zog PTFE nta tsis tshua muaj zog saum npoo (＜18 mN / m), qis dua li cov molten resin thiab cov nplaum. Nrog kev ua tau zoo uas tsis yog-stick zoo ib yam li cov khoom siv uas tsis yog-stick, nws tuaj yeem tev tawm yooj yim tom qab lamination tsis khawb FPC substrates los yog tawm hauv cov kua nplaum seem.

High-performance adhesive system xaiv Kom tsis txhob nws tus kheej-adhesive hloov ntawm daim kab xev, PTFE daim kab xev formulated nrog high-zoo silicone siab-rhiab nplaum nplaum yuav tsum tau saws. Premium silicone nplaum tuav kev ua haujlwm ruaj khov ntawm txog 260 ℃, ua kom tsis muaj cov kua nplaum nyob hauv lub sijhawm ntev. Qib ntsuas kub yuav tsum ua raws li cov txheej txheem (210-260 ℃).

Ua kom tiav Curing ntawm Adhesives Thaum lub sij hawm txheej thiab zus tau tej cov Aokai PTFE daim kab xev, lub sij hawm kho tsis zoo, kub los yog khiav ceev yuav ua rau kom tsis tiav cov nplaum curing, uas ua rau cov residual adhesive teeb meem nyob rau hauv daim ntawv thov tom ntej.
