Cov pob qij txha tsis tiav ntawm cov ntawv luam tawm Circuit Board-WAVE SOLDERING DEFECTS

Qhov tsis tiav solder fillet feem ntau pom ntawm ib sab boards tom qab yoj soldering.

Nyob rau hauv daim duab 1, qhov sib piv ntawm txhuas-rau-qhov yog ntau dhau, uas tau ua rau soldering nyuaj.Kuj tseem muaj pov thawj ntawm resin smear ntawm ntug ntawm lub ncoo.Tej zaum nws yuav ua tau, txawm tias ntawm qhov tsim no, txhawm rau txhim kho cov kev ua haujlwm zoo los ntawm kev txo lub kaum sab xis ntawm 6 txog 4 °.Qhov no txo ​​cov kua dej ua haujlwm ntawm nthwv dej tab sis tuaj yeem ua rau muaj qhov tshwm sim luv luv.Txo qhov kub ntawm nthwv dej kuj tau pom los daws qhov teeb meem.

Raws li kev qhia, qhov sib piv ntawm qhov sib piv feem ntau yog cov kab hlau lead ntxiv rau 0.010 ", uas yog cov lus qhia ib txwm siv rau kev nkag mus tsis siv neeg.

Cov lead-rau-qhov piv ntawm no yog ntau dhau

Tsis tiav solder fillets yog tshwm sim los ntawm qhov tsis zoo ntawm qhov sib piv rau cov hlau lead, cov kaum sab xis conveyor, qhov kub thiab txias ntau dhau ntawm cov ntaub qhwv.

Qhov piv txwv qhia hauv daim duab 1 yog qhov tshwm sim ntawm burring ntawm cov ntaub qhwv tooj liab.Thaum lub sij hawm drilling los yog xuas nrig ntaus, tooj liab ntawm lub rooj tsavxwm tau deflected nyob rau hauv qee qhov chaw, ua rau soldering nyuaj.Tib yam tuaj yeem tshwm sim yog tias cov resin smeared rau ntawm ntug ntawm cov ntaub qhwv.

Burring ntawm cov ntaub qhwv tooj liab ua rau qhov tsis xws luag.

Dab tsi yog qhov yoj solder pallet?

Wave solder pallets yog txoj kev txhim khu kev qha tshaj plaws thiab pheej yig ntawm cov khoom siv los ntawm lub qhov ntawm cov khoom siv hluav taws xob.… Lawv muab kev tiv thaiv thermal rau cov cheeb tsam hauv Circuit Court board uas muaj cua sov.Lub yoj solder fixture muab kev txhawb nqa rau PCB thoob plaws hauv cov txheej txheem nthwv dej.
