Cov kev cuam tshuam tsis sib xws thiab kev daws teeb meem ntawm PCB xuas nrig ntaus ({1)
Nrog kev txhim kho kom zoo ntawm cov khoom siv hluav taws xob sib dhos thiab cov kev xav tau ntawm kev sib tw ua lag luam, lub tshuab hluav taws xob tsis zoo no feem tau ua kom tiav sai. Nyob rau hauv txoj kev no, cov tseev kom muaj ntawm cov punching zoo ntawm ib leeg daim ntawv PCB daim ntawv daim hlau (ob peb leeg-ob tog thiab ob tog tsis-metallized epoxy-iav daim ntaub substrates tseem punched) ua qhov ntau dua thiab ntau dua. Hais txog PCB cov tuam ntxhab uas tam sim no siv hauv cov tshuab tsis siv neeg, cov kev tsis txaus siab thiab xa rov qab los ntawm cov xuas nrig ntaus tau nce mus rau thawj qhov chaw. Kab lus no tsuas yog nthuav qhia cov kev cuam tshuam sib xws thiab kev daws teeb meem ntawm PCB xuas nrig ntaus.

Ua rau
Qhov sib txawv nruab nrab ntawm concave thiab convex tuag yog qhov tsawg heev, uas ua rau cov kab nrib pleb ntawm ob sab ntawm convex tuag thiab concave tuag yam tsis muaj kev sib tshooj, thiab ob lub ntsej muag extrusion tshwm sim ntawm ob qho kawg ntawm tus ntoo khaub lig.
Qhov sib txawv ntawm qhov concave thiab cov punch yog qhov loj heev. Thaum lub punch poob qis, qhov tawg tshwm sim tuaj lig, thiab lub txiab ua tiav zoo li ntuag, ua rau cov khoom tawg kom tsis sib tshooj.
Qhov ntug ntawm rab hniav yog hnav los yog npawv lossis chamfered. Lub ntug ntawm cov hniav tsis zoo ua lub luag haujlwm ntawm kev faib tawm ntawm cov npoo, thiab tag nrho cov ntoo hla ua qhov tsim kua muag tsis xwm yeem.
Tshuaj
Xaiv cov khoob ntawm concave thiab convex tuag tubntxhais. Xws li cov punching thiab txiav yog nruab nrab ntawm kev rho tawm thiab ncab. Thaum cov punch txiav rau hauv cov khoom siv, ntug ntug tsim cov npoo, uas ua rau lub phaj kom muaj qhov sib luag ntawm txoj kab sib tsoo.
Kho lub fillet los yog chamfer tsim los ntawm concave thiab convex tuag sawv hauv lub sijhawm.
Ua kom txoj kev sib luag ntsug ntawm concave thiab convex tuag los ua qhov sib txawv ntawm qhov sib koom ua ke.
Nco ntsoov tias cov pwm tsim kab ntsug thiab ntsug.
