1. Ma'anar Yatsa Zinare
Yatsa ta zinariya, wacce aka fi sani da haɗin gefen, na'ura ce da ke saka ƙarshen ɗaya na PCB a cikin ramin mahaɗi. Tana amfani da fil ɗin mahaɗi a matsayin hanyar fita don haɗin waje na PCB don cimma ikon watsawa tsakanin kushin solder ko takardar jan ƙarfe da fil ɗin matsayi masu dacewa. Domin ƙara ƙarfin watsawa, juriya ga iskar shaka da juriyar lalacewa, galibi ana yi wa yatsun zinariya magani da plating na nickel gold ko ENIG. Saboda siffarsa kamar yatsa, ana kiransa da Gold Finger.
2. Hanyoyin gama saman PCBs na yatsan zinare
Hanyar kammala saman Gold Finger PCB tana da matuƙar muhimmanci ga aikinta da kuma yankunan da ake amfani da ita. Waɗannan su ne hanyoyi guda biyu da aka saba amfani da su:
1) Faranti na Nickel Gold
Famfon zinare na nickel wata hanya ce ta gama saman, kuma kauri na iya kaiwa inci 3-50. Yana da kyakkyawan juriya ga iskar oxygen da kuma juriya ga lalacewa, don haka ana amfani da shi sosai akan PCBs na yatsu na zinariya waɗanda ke buƙatar sakawa akai-akai da cirewa ko PCBs waɗanda ke buƙatar gogayya ta inji akai-akai. Duk da haka, saboda tsadar zinariya, yawanci ana amfani da famfon zinare na nickel ne kawai don magance yankunan gida kamar yatsun zinare. Fuskar wannan hanyar gama saman fari ne na azurfa, amma ƙarfinsa bai yi kyau ba.
2) YARDA
ENIG wata hanya ce ta gama saman da aka saba amfani da ita, wacce kauri yawanci ya kai inci 1 da kuma inci 3. ENIG yana da kyakkyawan yanayin watsawa, santsi a saman da kuma iya soldering, wanda hakan ya sa ake amfani da shi sosai a cikin PCBs masu inganci tare da ƙira kamar keyway, IC da aka ɗaure, BGA, da sauransu. Ga PCBs masu yatsa na zinariya waɗanda ba sa buƙatar juriya mai yawa, ana iya zaɓar dukkan tsarin ENIG na panel, wanda ke da ƙarancin farashi. Fuskar ENIG da aka gama rawaya ce ta zinariya.
3. Gargaɗi game da Tsarin Yatsa na Zinaren
Lokacin ƙirƙirar PCB mai yatsan zinare, akwai wasu muhimman abubuwan da ya kamata a lura da su musamman:
1) Saka juriyar yatsan zinariya
Ga PCBs waɗanda ke buƙatar sakawa akai-akai da cirewa, domin ƙara juriyar lalacewa na yatsun zinariya, yawanci yana da mahimmanci a yi amfani da ƙarfe mai ƙarfi na zinariya.
2) Rage girman yatsan zinariya
Yatsun zinare yawanci suna buƙatar yin chamfering, tare da kusurwar chamfering gabaɗaya na 45°. Kasancewar chamfers na iya rage haɗarin da ka iya tasowa, kamar yadda aka nuna a cikin hoton.
3) Buɗewar taga don abin rufe fuska na solder
Dole ne a yi wa murfin da ke kan yatsan zinariyar da buɗewar taga don dukkan toshewar abin rufe fuska na solder, ba tare da buƙatar ragar ƙarfe ba.
4) Nisa tsakanin abin rufe fuska da yatsan zinariya
Nisa tsakanin faifan solder da yatsan zinariya ya kamata ya yi daidai da ƙa'idodin ƙira, yawanci yana buƙatar faifan solder ya kasance aƙalla 1mm nesa da matsayin yatsan zinariya, gami da ta hanyar faifan solder.
5) Ƙarfin saman yatsan zinariya
Bai kamata a rufe saman yatsan zinare da tagulla ba.
6) Maganin yanke jan ƙarfe
Duk layukan da ke cikin yatsar zinare suna buƙatar maganin yanke jan ƙarfe, yawanci tare da faɗin yanke jan ƙarfe na kimanin mm 3. Wannan na iya rage bambancin hana tsatsa tsakanin yatsar zinare da layin hana tsatsa, yayin da kuma yana amfanar ESD.
Abubuwan da ke sama suna da fannoni da dama da ke buƙatar kulawa ta musamman yayin tsara PCB na yatsan zinariya don tabbatar da aminci da aikin yatsan zinariya.

4. Gargaɗi don Sarrafa Yatsa na Zinare
Idan kuna shirin amfani da PCB mai yatsa na zinariya, ga wasu matakan da za a ɗauka yayin sarrafa PCB na Rich Full Joy:
1. Kauri na PCB ɗin da za a iya yankewa shine daga 1.2mm zuwa 2.4mm. PCB ɗin da kauri ba ya cikin wannan kewayon ba za a iya yankewa ba.
2. Zurfi da kusurwar gefen da aka yanke yawanci suna tsakanin 20° da 45°. Nisa tsakanin yatsan zinare da gefen PCB ya kamata ya isa, galibi ana ba da shawarar ya kasance daga mita 0.6 zuwa 1.5mm, don guje wa lalata yatsan zinare.

Rich Full Joy ya ƙware wajen sarrafa PCBs na yatsar zinariya don tabbatar da inganci da aminci. Tsarinmu zai iya biyan buƙatun ƙira daban-daban da kuma samar da kyakkyawan aiki ga aikinku.

PCBs na zinare suna taka muhimmiyar rawa a fagen lantarki na zamani, kuma amincinsu da aikinsu ya dogara ne akan hanyoyin gama saman da cikakkun bayanai na ƙira. Ta hanyar zaɓar hanyoyin sarrafawa masu dacewa da kuma kula da mahimman la'akari da ƙira, yana yiwuwa a tabbatar da kyakkyawan aiki na PCBs na Gold Finger a cikin aikace-aikace daban-daban. Idan kuna buƙatar ayyukan sarrafa PCB na zinare masu inganci, da fatan za a yi la'akari da Ruizhi Xinfeng, kuma za mu yi farin cikin samar muku da tallafi.

4. Waɗanne matakai ya kamata a ɗauka yayin tsara PCB mai yatsan zinare?
Lokacin ƙirƙirar PCB na yatsan zinariya, yana da mahimmanci a kula da muhimman batutuwa kamar su chamfering, buɗewar taga don abin rufe fuska na solder, tazara tsakanin faifan solder da yatsun zinare, da kuma ƙarewar saman yatsun zinare.
5. Ta yaya za a tabbatar da ingancin PCB ɗin yatsa na zinariya?
Muna amfani da fasahar zamani da kuma ingantaccen tsarin kula da inganci don tabbatar da samar da kayayyaki masu inganci da inganci.
