Automotive-Grade Carbide PCB Micro Drill Bits Teem Tshiab Benchmark rau High-Kub Circuit Fabrication

Kev Taw Qhia

Thaum cov tuam txhab tsim tsheb fais fab thawb cov kev txwv ntawm qhov ceev ntawm lub voj voog, ib tiam tshiab ntawm cov khoom siv PCB micro drill bits tab tom daws cov teeb meem tseem ceeb ntawm kev tswj cua sov hauv cov khoom siv hluav taws xob. Tsim los ntawm tungsten steel carbide nrog metric precision, cov cuab yeej spiral-flute no sib xyaw ua ke 3.175mm shank txoj kab uas hla thiab 38mm tag nrho ntev kom ua tiav kev ua tau zoo hauv cov khoom siv kub siab FR-4 thiab polyimide substrates.

Qhov Tseem Ceeb ntawm Automotive

Cov txheej txheem tswj roj teeb EV niaj hnub (BMS) xav tau cov PCBs uas muaj peev xwm ua haujlwm tau 150 ° C + kub. Ib txwm muajcov khoom siv laum ntawm lub rooj tsavxwm luam tawmpoob qis nyob rau hauv cov xwm txheej no, raug kev txom nyem sai dua thiab phab ntsa qhov tawg.

Kev Ntsuas Geometry Uas Muaj Kev Ntsuas Zoo Hauv Kev Ua Haujlwm

• Qhov Zoo ntawm Spiral Flute: 38° helix angle nrog cov iav-polished flutes txo qhov chip adhesion los ntawm 70% piv rau cov qauv tsim kev lag luam, tshem tawm smear hauv 0.3mm micro-vias
• Kev sib xws ntawm cov ntsuas: tsawg dua 2 micron qhov loj me rau cov laug cam tsheb uas muaj kev nyab xeeb tseem ceeb

Kev Tshawb Fawb Txog Daim Ntawv Thov:

Cov cuab yeej no ua tau zoo heev hauv kev khawb silicon carbide-embedded PCBs, qhov twg cov khoom siv ib txwm muaj kev puas tsuaj loj heev. Cov kev hloov tshiab tseem ceeb:

Cov ntug txiav me me tiv thaiv cov substrate chipping

Nano-crystalline pob zeb diamond txheej rau ntawm lub ntsej muag flute

Xaus lus

Cov carbide noPCB micro laum ntsissawv cev ntau dua li kev txhim kho me ntsis xwb. Lawv muab kev ruaj khov thermal thiab metric precision uas tsim nyog rau cov khoom siv hluav taws xob tiam tom ntej - hloov kev khawb los ntawm qhov chaw siv nyiaj mus rau qhov zoo dua.
