Mashoko okutanga:

Nekukurumidza kukurumidza kwe PCB indasitiri, pcb iri kufamba zvishoma nezvishoma ichienda kunongedzo yeiyo chaiyo yakatsetseka mutsara, aperture diki, yakakwira chimiro (6: 1-10: 1). The mugomba mhangura chinodiwa 20-25um, uye DF mutsetse daro ≤4mil bhodhi. Kazhinji, makambani ePBB ane dambudziko re electroplating film clamping. Firimu clip inokonzeresa yakananga pfupi dunhu, inokanganisa iyo CHIMWE-NGUVA goho rePCBboard kuburikidza neAOI kuongorora, yakakomba firimu clip kana mapoinzi haigadziriswe zvakananga zvichikonzera chinyorwa.

Graphic mufananidzo we graphic electroplating clip firimu dambudziko:

Maitiro ekugadzirisa dambudziko rePCBboard board yakanamirwa clip firimu

Analysis of musimboti pcb bhodhi clamping firimu

(1) Kana ukobvu hwemhangura hwemagetsi hwakagadzirwa nemagetsi hwakawanda kupfuura hukobvu hwefirimu yakaoma, zvinokonzeresa kufirimu. (The yakaoma firimu ukobvu zvavo pcb fekitari iri 1.4mil)

(2) Kana ukobvu hwemhangura netini pane graphic electroplating tambo inodarika kuwanda kwefirimu yakaoma, firimu clip inogona kukonzerwa.

Pcb bhodhi clamping firimu ongororo

1. Zviri nyore kutema firimu bhodhi mifananidzo uye mapikicha

Nzira yekugadzirisa sei dambudziko rePCBboard board plating clip firimu?

MUFIGI. 3 uye FIG. 4, inogona kuonekwa kubva pamifananidzo yeplate yepanyama iyo dunhu iri rakaomarara, uye paine musiyano mukuru pakati peyero yehurefu nehupamhi mukugadzirwa kweinjiniya uye dhizaini, uye kugoverwa kwakashata kwazvino. Iyo shoma tambo musiyano weD / F ndeye 2.8mil (0.070mm), iyo diki diki iri 0.25mm, hombe ukobvu iri 2.0mm, chimiro chechikamu ndi8: 1, uye gomba mhangura rinodikanwa kuti rinopfuura 20Um. Izvo ndezvemaitiro akaoma bhodhi.

2. Kuongorora kwezvikonzero zvekunamatira kwefirimu

Ikozvino kuwanda kwemifananidzo yakajeka electroplating yakakura uye iyo yendarira yakanamirwa yakanyanya kukora. There is no edge strip at both ends of the fly bar, and thick film is plated in the high current area. Iko kukanganisa kwazvino kwemombe kwakakura kupfuura iyo chaiyo yekugadzira ndiro. Ndege yeC / S uye ndege yeS / S zvakabatana zvakapesana.

Plate clip ine diki 2.5-3.5mil nzvimbo.

Iko kugoverwa kwazvino hakusi yunifomu, yemhangura yakakwenya humburumbira kwenguva yakareba pasina kuchenesa anode. Yazvino isiriyo (isiriyo mhando kana isiri ndiro nzvimbo) Dziviriro yazvino nguva pcb bhodhi mumhangura humburumbira hwakareba.

 Iyo dhizaini dhizaini yeprojekiti haina musoro, inoshanda electroplating nzvimbo yeiyo projekiti giraidhi haina kunaka, nezvimwe. PCB board line gap is too small, difficult board line graphics special easy clip film.

Inoshanda inovandudza chirongwa che clip firimu

1. kuderedza girafu yazvino kuwanda, kwakakodzera kuwedzerwa kwendarira yakanamirwa pamhepo nguva.

2. Wedzera kuisuka kwemhangura hukobvu hwendiro nenzira kwayo, kudzikisa kuenzana kwemhangura kwegirafu nenzira kwayo, uye zvishoma kudzora kuisesa mhangura kukora kwegrafu.

3. Ukobvu hwemhangura hwepasi yakarongedzwa hwashandurwa kubva pa0.5OZ kuenda pa1 / 3oz yepasi yendarira. Iyo yekukanda mhangura ukobvu hweplate inowedzerwa neinenge 10Um yekudzikisa iyo iripo density yeiyo graph uye iyo yakanamirwa pamhangura ukobvu hwegirafu.

4. Yezve bhodhi nzvimbo <4mil kutenga 1.8-2.0mil yakaoma firimu yekuyedza kugadzirwa.

5. Zvimwe zvirongwa zvakaita sekushandurwa kwedesetet dhizaini, kushandurwa kwemubhadharo, kubvumidzwa kwemutsara, kucheka mhete uye PAD zvinogona zvakare kudzikisa kugadzirwa kweiyo firimu clip.

6. Electroplating kugadzirwa kudzora nzira yefirimu ndiro ine diki gap uye nyore clip

1. FA: Chekutanga edza kumucheto kusungira matanda pamativi ese epabhodhi. Mushure mekukora kwemhangura, mutsetse upamhi / mutsetse daro uye impedance vanokodzera, pedzisa kutora iyo flobar bhodhi uye pasa AOI kuongorora.

2.Fading fading: yeplate ine D / F linegap <4mil, iyo etching kumhanya kwekupera firimu inofanira kugadziriswa zvishoma nezvishoma.

3. Unyanzvi hwevashandi veFA: teerera kutarisisa kwehuwandu hwehuwandu kana uchiratidza kubuda kwazvino kweplate neyakareruka clip firimu. Kazhinji, iyo shoma tambo musiyano weplate iri pasi pe3.5mil (0.088mm), uye ikozvino kuwanda kwemagetsi emhangura inodzorwa mukati me ≦ 12ASF, izvo zvisiri nyore kuburitsa clip firimu. Pamusoro pemutsara mifananidzo inonetsa zvikuru bhodhi sekuratidzwa pazasi:

Maitiro ekugadzirisa dambudziko rePCBboard board yakanamirwa clip firimu

Iko kushomeka kweD / F kupenga kweiyi graphic bhodhi ndeye 2.5mil (0.063mm). Pasi pemamiriro ekufananidzwa kweiyo gantry electroplating mutsara, zvinokurudzirwa kushandisa ≦ 10ASF yazvino density test FA.

Nzira yekugadzirisa sei dambudziko rePCBboard board plating clip firimu?

Iyo shoma tambo musiyano weiyo graphic board D / F iri 2.5mil (0.063mm), iine yakazvimirira mitsara uye isina kuenzana kugovera, haigone kudzivisa njodzi yemufirimu clip pasi pemamiriro ehutano hwakaenzana weelectroplating mutsara wevakawanda vagadziri. Ikozvino kuwanda kwemifananidzo graphic electroplating mhangura ndeye 14.5ASF * 65 maminetsi kugadzira firimu clip, zvinokurudzirwa kuti girafu yemagetsi zvazvino uno ≦ 11ASF bvunzo FA.

Chiitiko chako uye pfupiso

Ndave ndakashanda muPCB yekuita chiitiko kwemakore mazhinji, kazhinji pese pcb fekitori inogadzira bhodhi ine diki mutsara gap zvakanyanya kana kushoma ichave nedambudziko rekubaya bhaisikopo, mutsauko ndewekuti fekitori yega yega ine chikamu chakasiyana chechinetso chakashata chefirimu, mamwe makambani ane mashoma dambudziko rekudzvanya bhaisikopo, mamwe makambani ane mamwe matambudziko ekuvhara firimu. The following factors are analyzed:

1. imwe neimwe kambani pcb bhodhi chimiro mhando rakasiyana, pcb yekugadzira maitiro kuoma kwakasiyana.

2. Kambani yega yega ine akasiyana manejimendi modhi uye nzira.

3. kubva pakuona kwekudzidza kweangu mazhinji makore eakaunganidzwa ruzivo, kune diki ndiro inofanirwa kutarisisa kune yekutanga mutsara gapuro inogona chete kushandisa diki yazvino density uye yakakodzera kuwedzera nguva yenguva yendarira, iwo aro mirairo maererano ruzivo rwehuwandu hwazvino uye iyo yemhangura yakashandiswa kuongorora nguva yakanaka, teerera kune nzira yeplate uye nzira yekushandisa, yakanangana netambo yepasi kubva ku4 mil ndiro kana zvishoma, edza kubhururuka iyo FA bhodhi inofanirwa kuve neAOI kuongorora pasina kapsule, Panguva imwecheteyo, zvakare inoita chinzvimbo mukudzora kwemhando yepamusoro uye kudzivirira, kuitira kuti mukana wekugadzira clip yemafirimu mukugadzira kwakawanda uve mudiki kwazvo.

Mune maonero angu, yakanaka pcb mhando inoda kwete chete ruzivo uye hunyanzvi, asiwo nzira dzakanaka. Izvo zvakare zvinoenderana nekuurayiwa kwevanhu mubazi rezvigadzirwa.

Graphic electroplating yakasiyana neese ndiro electroplating, musiyano mukuru uripo mumutsetse mifananidzo yemhando dzakasiyana dzeplate electroplating, mamwe mabhodhi emutsetse mapikicha pachawo haana kugoverwa zvakaenzana, kuwedzera kune yakanaka mutsara upamhi uye chinhambwe, pane mashoma, a mitsara mishoma yakasarudzika, maburi akazvimirira ese marudzi akasarudzika emitsara mifananidzo. Naizvozvo, MUNYORI anonyanya kuda kushandisa FA (yazvino chiratidzo) hunyanzvi kugadzirisa kana kudzivirira dambudziko remufirimu gobvu. Iyo yekuvandudza matanho renji idiki, inokurumidza uye inoshanda, uye maitiro ekudzivirira ari pachena.
