2 Wosanjikiza HASL FR4 Half Hole PCB

Chitsulo theka dzenje (poyambira) ndi dzenje pambuyo dzenje pambuyo pobowola wachiwiri, mawonekedwe ndondomeko, ndipo potsiriza kusunga zitsulo dzenje (poyambira) theka, anangoti mbale m'mphepete metallized dzenje kudula theka, mbale m'mphepete theka-zitsulo dzenje ndondomeko. ndi njira yokhwima kwambiri.

Momwe mungayang'anire khalidwe la mankhwala mutatha kupanga dzenje lachitsulo m'mphepete mwa mbale.Monga dzenje khoma mkuwa prickle, zotsalira wakhala njira yovuta.Mzere wathunthu wa mabowo opangidwa ndi theka-metallized m'mphepete mwa mbale zotere PCB, yodziwika ndi kabowo kakang'ono, komwe amagwiritsidwa ntchito kwambiri pa bolodi, monga gawo la mbale ya master, yomwe mabowo opangidwa ndi theka-metallized amawotcherera ku zikhomo za mbale mbale ndi zigawo zikuluzikulu.

Ngati pali nsana zamkuwa mu dzenje theka-metallized, pamene wopanga kuwotcherera, izo zidzatsogolera ku kuwotcherera phazi si olimba, pafupifupi kuwotcherera, kwambiri adzachititsa mlatho pakati pa zikhomo ziwiri dera lalifupi.Onse pobowola ndi mphero, malangizo a kasinthasintha wa SPINDLE ndi wotchi, kuteteza kutambasuka kwa wosanjikiza metallization pa processing ndi kulekana kwa wosanjikiza metallization ku khoma dzenje, ndi kuonetsetsa kuti nsana zamkuwa ndi zotsalira sizidzapangidwa pambuyo processing. .Kukhala wamkulu kuposa malo opanda kanthu a gong.
