1. Pamwamba pa PCB: Ossss, isl, isl wopanda masikono, a Emig, Golide wa bolodi yonse, agolide ...

OsP: Mtengo wotsika, wogulitsirana bwino, malo osungira nthawi yayitali, nthawi yochepa, ukadaulo wazachilengedwe, wosalala ... wosalala ...

Hall: Nthawi zambiri ndi mitundu yosiyanasiyana HDI PCB Sammes (4 - 46), yakhala ikugwiritsidwa ntchito ndi makompyuta ambiri, makompyuta, zida zamankhwala ndi magawo ofufuza.

Chala chagolide: Ndi kulumikizana pakati pa slot yokumbukira ndi chitsutso, zizindikiro zonse zimatumizidwa ndi chala chagolide.
Zizindikiro zagolide za zigawo zingapo zagolide zomwe zimapangidwa ndi golide, zomwe zimatchedwa kuti "lala wagolide" chifukwa cha manja awo okhala golide ndi zala zawo ngati zala zawo. Chala chagolide chimagwiritsa ntchito njira yapadera kuti ikhale yamkuwa yokhala ndi golide, yomwe imalimbana ndi maxidation komanso ochititsa chidwi kwambiri. Koma mtengo wagolide ndi wokwera mtengo, mafinya ang'ono apano amagwiritsidwa ntchito m'malo mokumbukira. Kuyambira zaka 90, zosonyeza kuti matani, amakumbukira, kukumbukira, ndi zida zamakanema zokhala ndi zingwe zokhala ndi zingwe zokhala ndi ma cell ogwiritsa ntchito golide, motero mtengo uli ndi zochepa.

2. Chifukwa chiyani bolodi la golide?
Ndi kuphatikiza kwa ice yayikulu ndi yayitali kwambiri, i i i i i i ic modzi kwambiri. Pomwe njira yopyapwiritsira yolumikizira tini ndizovuta kuwombera pakhoma lamphamvu, zomwe zimabweretsa vuto lakukweza kwa SMT; Kuphatikiza apo, alumali moyo wamiyala kupopera mbale ndi lalifupi kwambiri. Komabe, mbale yagolide imathetsa mavutowa:

1.) Pakuti ndi mapiri a Mount Mount Mount Mount Mount Mount Mount Mount, chifukwa kufulumira kwa pad yojambulidwa ndi mtundu wa Wogulitsa, motero, pulawo yonse yamoto

2. Kupatula apo, PCB yolembedwa ndi golide m'madigiri ya mtengo wa zitsanzo poyerekeza ndi mbale za pewter

Koma ndi zochulukirapo komanso zokulirapo zowonda, mulifupi, kutalika kwafika 3-4mil

Chifukwa chake, zimabweretsa vuto la mabwalo afupifupi a waya wagolide: Ndi kuchuluka kwa chizindikirocho, chiwopsezo cha kutumiza siginecha mu zokutira zingapo chifukwa chakhungu chimakhala zochulukirapo

.

3. Chifukwa chiyani kugwiritsa ntchito kumiza PCB?

Pali zinthu zina za kumiza PCB PCB ikuwonetsa ngati pansipa:

1.) Kapangidwe kalikonse kopangidwa ndi kumiza golide ndi kutumizirana golide ndi kosiyana, mtundu wa golide womizidwa udzakhala wabwino kwambiri kuposa kupangira golide ndipo kasitomala amakhala wokhutira kwambiri. Kenako kupsinjika kwa mbale yagolide kumakhala kosavuta kuwongolera, komwe kumatha kusintha kwa zinthuzo. Nthawi yomweyonso chifukwa golide ndi wofalikira kuposa golide, kotero mbale yagolide savala - golide wosagwirizana ndi golide.

2.) Kumiza golide ndikosavuta kuwira kuposa kusindikizidwa golide, ndipo sikupangitsa kuti madandaulo azithunzi komanso madandaulo a makasitomala.

3.) Golide wa Nickel amangopezeka padzenje lotentha pa enig pcb, kufalitsa chizindikiro pakhungu kumachitika, komwe sikukhudza chizindikirocho, komanso osatengera madera a waya wagolide. Wogulitsa msiri mbali amaphatikizidwa kwambiri ndi zigawo za mkuwa.

4.) Kupanga kristo kumiza golide ndi wowonda kuposa kupanga golide, ndikovuta kupanga makutidwe

5.) Sipadzakhalaponso patali pa nthawi yomwe ikulipidwa

6.) Kulefuka ndi ntchito yautumiki wa mbale ya golide ndiyabwino ngati mbale yagolide.

4.. Minal Gold vs golide

Pali mitundu iwiri yaukadaulo wagolide: imodzi ndi malo opangira zamagetsi, inayo ndi imiya golide.

Chifukwa kudula golide, zomwe zimapangitsa kuti tanizi zachepetsedwa kwambiri, ndipo zotsatira za golide ndibwino; Pokhapokha wopangayo amafuna kumanga, kapena tsopano opanga ambiri asankha njira yomira golide!

Nthawi zambiri, mankhwalawa a PCB amatha kugawidwa m'njira zotsatirazi: Kulemba kwa golide (ma eltoftatution, malo osakira Pa timiyala osauka (kudya tini osauka) izi ngati kuchotsedwa kwa opanga maste ndi zifukwa zopangira zakuthupi.

Pali zifukwa zina za vuto la PCB:

Kusindikiza PCB, kaya pali mafuta ophatikizira poto poto, imatha kuletsa kufiyira; Izi zitha kutsimikiziridwa ndi mayeso a msirikali

3. Phukusi lowala silimadetsedwa, lomwe limatha kuyesedwa ndi ion kuipitsidwa.

Pafupifupi pamwamba:

Kusindikiza golide, kumatha kupanga nthawi yosungirako za PCB nthawi yayitali, ndipo posintha kutentha kwapadera ndi chinyezi (poyerekeza ndi mankhwala ena), nthawi zambiri amatha kusungidwa pafupifupi chaka chimodzi; Phulusa kapena kutsogolera Free Free Chithandizo chachiwiri, malo awiriwo pachipatalachi mu kutentha kwanyengo ndi chinyezi Ndipo sungani kwa miyezi itatu! Pa mphamvu ya timin, golide, maosspo, timiyala takhala chimodzimodzi, opanga makamaka amalingalira momwe mtengo!
