Extended Multilayer Board

Raws li cov neeg muaj feem cuam tshuam los ntawm cov neeg tsim khoom lag luam txuas ntxiv, cov txheej txheem ntau txheej, tseem hu ua plywood, yog peb txheej lossis ntau txheej phaj zoo li cov khoom tsim los ntawm kev tig ntoo rau hauv veneers lossis npaj ntoo rau hauv nyias ntoo, thiab ces gluing nrog nplaum. Nws yog ib yam khoom siv rooj tog. Feem ntau, ib txheej khib nyiab yog siv los khi cov veneers uas nyob ib sab mus rau ib leeg nyob rau hauv txoj kab ntev.

Feem ntau, cov yas hom plywood thiab cov txheej sab hauv yog symmetrical ntawm ob sab ntawm nruab nrab txheej los yog cov tub ntxhais. Ntxiv mus, cov txheej txheem ntau txheej yog tag nrho cov ntoo ntuj, uas tuaj yeem kho qhov kub thiab av noo hauv tsev, thiab yooj yim rau nruab.

Feem ntau hais lus, kev tsim cov txheej txheem ntawm multilayer board feem ntau yog thawj zaug siv cov txheej txheej sab hauv thiab tom qab ntawd siv txoj kev luam ntawv etching los ua ib sab lossis ob sab hauv qab phaj. Thiab muab tso rau hauv cov txheej txheem interlayer, cua sov, xovxwm, daim ntawv cog lus, thiab tom qab ntawd cov txheej txheem xuas nrig ntaus yog tib yam li cov txheej txheem plating ntawm ob txheej txheej. Cov txheej txheem tsim khoom yooj yim no tsis tau hloov pauv ntau piv nrog rau xyoo 1960s, tab sis nrog kev txhim kho cov ntaub ntawv thiab cov txheej txheem thev naus laus zis (xws li kev sib koom tes thev naus laus zis, uas daws cov kua nplaum seem tsim tawm thaum lub sijhawm drilling, thiab kev txhim kho zaj duab xis), cov khoom ntawm cov khoom txuas nrog ntau yam. -txheej daim hlau kuj muaj ntau haiv neeg.
