Nei ENIG PCB Kugadzira Kwakanaka kune Yakakwira-Frequency Zvishandiso

Semusana wemagetsi emazuva ano, maPCB anokosha pakushanda kwezvigadzirwa zvemagetsi. Pakati pekupedzisa kwakasiyana kwepamusoro kwakaiswa kumaPCB, Electroless Nickel Immersion Gold (ENIG) inozivikanwa zvakanyanya nekuita kwayo kwakasiyana uye kuvimbika. Highleap Electronic inogadzira ENIG PCBs nemhando yepamusoro, mutengo wakaderera, kuita kwakagadzikana, uye kugona kugadzira 2/2mil mutsara upamhi uye gomo ENIG PCB. Muchinyorwa chino, isu tichaongorora zvakadzika mukati mepakati maitiro ekugadzira ENIG PCB, kuratidza zvakanakira zvayo, kuongorora zvinonetsa, uye kutsanangura kuti nei ichiramba iri sarudzo yepamusoro kumaindasitiri mazhinji, kubva kune zvemagetsi zvevatengi kusvika kune aerospace.

Chii chinonzi ENIG (Electroless Nickel Immersion Gold)?

ENIG, iyo inomiririra Electroless Nickel Immersion Goridhe, inzvimbo inoshanda kwazvo yekupedzisa inoshandiswa mukugadzira PCB. Iine mitsara miviri yakasiyana: nickel layer inoteverwa negoridhe rakatetepa. Basa rekutanga rematanho aya kuchengetedza pasi pasi mhangura kubva kune oxidation apo ichipa yakanyatsovimbika pamusoro peiyo solder zvikamu.

Pamusoro pekuchengetedza PCB kubva mukuora uye kukuvadzwa kwemuchina, iyo ENIG kupedzisa kunogonesa kutengeswa, magetsi conductivity, uye kugadzikana kwekupisa, zvichiita kuti ive yakanyanya kunaka kune yakanaka-pitch zvikamu uye yakakwirira-frequency application.

Iyo ENIG Maitiro: Yakadzama Matanho eKugadzira

Iyo ENIG maitiro anosanganisira akati wandei akakosha matanho anofanirwa kudzorwa nekuchenjera kuti ave nechokwadi chekupedza kwemhando yepamusoro. Pano, tinodonhedza nhanho imwe neimwe zvakadzama:

1. PCB Surface Kugadzirira

Kusati kwaitika chero plating, iyo yemhangura yePCB inofanirwa kunyatsogadzirira. Izvi zvinosanganisira kuchenesa, micro-etching, uye activation yemhangura kuti ive nechokwadi chekunamatira kwakaringana kwenickel layer. Kusachena kwakadai sekusvibiswa kwe organic uye oxidation kunobviswa kuburikidza nealkaline yekuchenesa mhinduro. Mushure mezvo, iyo mhangura yemhangura ine micro-yakadzika kuti igadzire roughened texture, iyo inowedzera kunamatira kwe nickel layer.

2. Nickel Deposition (Electroless Nickel)

Mune electroless nickel plating nhanho, nickel-phosphorus alloy inoiswa pamusoro pemhangura ichishandisa nzira yekudzikisa kemikari. Iyi plating inoitwa pasina kushandiswa kwemagetsi ikozvino, iyo inoita kuti ive yakanaka kune yakaoma geometri uye nzvimbo dzisiri-conductive. Iyo nickel inoshanda sechivharo chinodzivirira chendarira iri pasi, kudzivirira oxidation uye corrosion panguva yehupenyu hwePCB.

Kazhinji, nickel layer ukobvu hunobva pa3-7 microns. Iyo phosphorus yemukati mu nickel inogona kusiyanisa pakati pe2% ne14%, iyo inokanganisa kushora kwekupedza. Yepamusoro phosphorus mazinga anotungamira kukuwedzera kwekusagadzikana uye kusapfeka kupfeka, nepo yakaderera phosphorus mazinga anovandudza solderability.

3. Kunyudza Gold Deposition

Kutevera nickel plating, PCB inonyudzwa mumushonga une maion egoridhe. Kunyudzwa kwegoridhe uku kunobva kwachinja, uko maatomu egoridhe anotsiva maatomu enickel ari pamusoro, achigadzira goridhe rakatetepa, rakafanana. Iyo yekunyudza yegoridhe layer inowanzo pakati pe0.05-0.23 micrometers gobvu.

Iyi goridhe layer inoshanda zvakati wandei zvakakosha:

• Ngura kudzivirira: Ndarama inopesana zvakanyanya neoxidation, ichiita kuti PCB ichengetedze kushanda kwayo nekufamba kwenguva, kunyanya munzvimbo dzakaoma.
• Low-contact resistance: Iyo yegoridhe layer inosimudzira mashandiro emagetsi ePCB nekupa yakagadzikana uye yakaderera-inodzivirira yekuonana pamusoro peiyo solder process.
• Solderability: Iyo yegoridhe layer inovandudza solderability yePCB, zvichiita kuti zvive nyore kuwana akavimbika solder majoini panguva yekuungana.

4. Rinsing, Drying, uye Quality Inspection

Kana nzira yekunyudza yegoridhe yapera, PCB inogeza kubvisa chero makemikari asara. Iyo PCB inozoomeswa, uye kuongororwa kwemhando yekudzora kunoitwa kuti ive nechokwadi chekuti kupedzisa kunosangana nemiyero yese inodiwa. Izvi zvinosanganisira ongororo yekuona yekufanana uye yekunamira bvunzo kuti ive nechokwadi chekuti nickel negoridhe zvidimbu zvakasungwa zvakachengeteka.

Mabhenefiti Akakosha e ENIG Surface Finish

ENIG inopa akati wandei akasiyana mabhenefiti pamusoro pemamwe PCB anopedzisa, ayo anoita kuti ive sarudzo inosarudzika mune akawanda epamusoro-kuita maapplication.

1. Superior Surface Planarity

Imwe yeanonyanya kukosha mabhenefiti eENIG ndeye yakasarudzika yepasi planarity. Iyo yakatsetseka uye yakati sandara nzvimbo yakakosha pakuunganidza zvikamu zvakatsetseka. ENIG inova nechokwadi chekuti zvinhu zvakaita seBall Grid Arrays (BGAs) uye chip-on-board (COB) mapakeji anoita yakavimbika magetsi kuonana, zvichideredza mukana wekuremara senge inotonhora solder majoini.

2. High Durability uye Hurefu Hweupenyu

ENIG inozivikanwa nehupenyu hwayo hurefu hwesherufu uye kusimba. Iyo nickel layer inopa yakaoma, isingapfeki nzvimbo, nepo goridhe layer ichidzivirira kubva kune oxidation uye ngura. Aya maitiro anoita kuti ENIG ive sarudzo yakanakira maPCB anoshandiswa munzvimbo dzakaomarara, senge anowanikwa mumhepo, mota, uye zvemagetsi zvekurapa.

3. Kuenderana nezvose zviri zviviri Lead-Free uye Lead-Based Soldering

ENIG inoenderana zvizere nezvose zviri zviviri lead-isina uye lead-based soldering maitiro, zvichiita kuti ive yakawanda kwazvo. Uku kuchinjika kwakakosha zvakanyanya sezvo indasitiri inoenda kune RoHS kutevedzera uye magariro ekugadzira maitiro. ENIG inovimbisa majoini anovimbika ekutengesa mune ese ari maviri mamiriro, zvichiita kuti ive sarudzo yakanaka kune vagadziri vanoda kuteedzera mitemo yenyika.

4. Excellent Electrical Performance

ENIG inofarirwa nekushomeka kwayo-kusangana kuramba uye yakakwirira conductivity, kuve nechokwadi kushoma kwechiratidzo kurasikirwa mune yakakwirira-frequency application. Izvi zvakanyanya kukosha muminda senge nharembozha, RF (redhiyo frequency) application, uye magetsi emagetsi, uko kushanda kwemagetsi kwakakosha.

5. Kuwedzerwa Solderability

Iyo yakatetepa yegoridhe layer ye ENIG inosimudzira iyo solderability yePCB. Inovimbisa kuti majoini e solder anoumba akavimbika, achideredza mikana yekutonhora solder majoini uye bhiriji. Izvi zvinonyanya kukosha kune yepamusoro-soro tekinoroji (SMT) uye chip-on-board (COB) matekinoroji, uko kunaka kwemajoini ekutengesa kunokanganisa zvakananga kushanda uye hupenyu hurefu hwechigadzirwa chekupedzisira.

Kuenzanisa ENIG neImwe PCB Surface Inopedza

Kuti unzwisise zvirinani kukosha kwe ENIG, ngatiienzanise nemamwe akajairwa PCB pamusoro pekupedzisira:

• HASL : Kunyange hazvo HASL isingadhuri uye ichipa mukana wakanaka wekusonesa, haina planarity yepamusoro inodiwa kune zvikamu zvinopenya zvakanaka. Kupera kweHASL kwakavakirwa pa lead kunogonawo kuva dambudziko mumashandisirwo emagetsi akawanda, uko nzvimbo isina kusimba inogona kukonzera kukanganiswa kwechiratidzo.

• OSP : OSP inzira yakachipa pane ENIG, ichipa chifukidziro chekudzivirira pamusoro pemhangura. Zvisinei, inopa kusasimba kwakanyanya kwe oxidation uye haina kukodzera munzvimbo dzinoda kugara kwenguva refu, senge mukushandiswa kwemauto kana kwekurapa.

• Sirivha Inopinda Mumvura (ImAg) : Kufanana neENIG, ImAg inopa kugona kusungirira zvakanaka uye kurongeka kwepamusoro. Zvisinei, ImAg inonyanya kusvibiswa uye kuomeswa nekufamba kwenguva, zvichiita kuti isavimbike kushandiswa kwenguva yakareba.
