Lub 14 txheej rov qab drilling board ntawm Uniwell Circuits yog tsuas yog siv nyob rau hauv cov teb uas yuav tsum tau nruj teeb liab kev ncaj ncees, xws li siab - kev sib txuas lus ceev, servers, thiab cov ntaub ntawv chaw. Los ntawm cov txheej txheem rov qab drilling, tsis muaj txiaj ntsig los ntawm qhov seem seem (STUBs) raug tshem tawm, txo cov teeb meem kev xav, ncua sijhawm, thiab cuam tshuam, thiab txhim kho kev sib kis zoo.
Cov txiaj ntsig tseem ceeb ntawm rov qab drilling tshuab yog:
Txhim kho cov teeb liab kev ncaj ncees: Laum tawm tsis txuas los ntawm - qhov ntu (STUBs) kom tsis txhob muaj kev cuam tshuam thiab tawg thaum lub sijhawm siab - teeb liab kis tau tus mob.
Tswj qhov seem seem ntev: Feem ntau, cov seem STUB yog tswj nyob rau hauv thaj tsam ntawm 50-150 μ m kom sib npaug ntawm cov khoom nyuaj thiab cov teeb liab ua haujlwm.
Txhawb siab- theem tsim: haum rau ntau- txheej boards nrog 14 lossis ntau txheej txheej, ua tau raws li qhov yuav tsum tau ua ntawm kev sib koom ua ke ntawm kev sib txuas.
Nws cov khoom tsis raug cai muaj xws li:
| Board qauv | 14 txheej |
| Cov khoom sib xyaw | RO4003C + HTG sib xyaw ua haujlwm siab |
| Qhov muag tsis pom qhov ntau | 1-4 txheej lossis 1-9 txheej |
| Backdrilling muaj peev xwm | txhawb nqa ob qhov drilling nrog qhov tob tswj tau, nrog cov seem seem (Stab) Tsawg dua lossis sib npaug rau 2mil (kwv yees li 50.8 μ m) |
| Aperture specification | Qhov muag tsis pom qhov aperture tsawg li 0.15mm |
| Cov txheej txheem tshwj xeeb | resin plug qhov, tuab tooj liab tsim (xws li 4Oz), thiab lwm yam |
