Usambofa wakaderedza P CB Half-Hole Boards
Chii chinonzi PCB hafu-gomba? Half vias mitsara yemakomba akacherwa achitevedza miganhu yePCB nechinangwa chekugadzira. Kana maburi akaputirwa nemhangura, mapendero acho anochekwa kuitira kuti maburi ari pedyo nemuganhu ave nehafu. Micheto yePCB inotaridzika senzvimbo yakafukidzwa nemhangura mukati memakomba.
Chii chinangwa chehafu-makomba? Modular PCBs dzakagadzirwa nehafu vias, kunyanya kuti zvive nyore kutengesa, diki module saizi uye zvinoshanda zvinodiwa. Kazhinji, hafu-gomba inogadzirwa muPCB imwe kumucheto kwegomba, mune gong chimiro gong hafu, ichisiya chete hafu yegomba muPCB, inowanzozivikanwa sehafu-gomba.
Dhizaini yekugadzirwa kwehafu-gomba mahwendefa
1. Minimum hafu-gomba
Minimum hafu-gomba process yekugadzira inokwana 0.5mm, iyo fungidziro ndeyekuti gomba rinofanira kunge riri pakati peiyo profile line, zvinoreva kuti panofanira kunge paine 0.25mm maburi mundiro. Kana zvisina kudaro, mhangura yemadziro egomba ichawa panguva yekugadzira, zvichiita kuti pasina gomba remhangura, chigadzirwa chakapedzwa hachigoni kushandiswa.
2. Half-gole spacing
Iyo shoma yakapedzwa aperture yehafu-gomba board ndeye 0.5mm, uye iyo aperture inoda kubhadharwa mukugadzira mushure mekubhadharwa kwehafu-gomba uye hafu-gomba spacing inoda kuoneswa pa ≥ 0.35mm, saka dhizaini yehafu-gomba spacing inoda kuve ≥ 0.45mm. Half-gomba inoenderana nemapedhi emutsara mushure mekubhadharwa kuti ive nechokwadi chekuti ≥ 0.25mm, hafu-gomba inoenderana ne soldermask hwindo pads uye mapedhi inofanira kuitwa pakati pebhiriji re soldermask.
3.Dzivirira kusangana nemarata mapfupi dunhu
Yakagadzirirwa rectangular pini, hafu-gomba aperture uye padhi upamhi, nezvimwewo, panguva ino vamwe mainjiniya anogona kuwedzera hupamhi padhi kuti ive nechokwadi kuti gomba mhete, tichiregeredza spacing mapedhi ari musangano welding muitiro zvinotungamirira kunyange tin pfupi-dunhu. Kutaura zvazviri, hafu-gomba inongoda kuita gomba kune welding mhete inogona kuva, pasina kuwedzera hupamhi hwepini yose, nokuti hafu yemakomba kunze kwebhodhi ichave yakanyungudutswa pakuumbwa.
4. Half-hole collage
Iyo hafu-gomba bhodhi marongero anofanirwa kunge aine hafu-gomba chinzvimbo nekuruboshwe, zvichiita kuti zvive nyore kuumba nekugaya hafu-gomba. MuPCB dhizaini collage inofuratira iyi poindi, nekuti vashoma mainjiniya ekugadzirisa anga aenda kuPCB fekitori kuti anzwisise kuti hafu-gomba inogadzirwa sei. Kune hafu-gomba zvigadzirwa zvakakosha, kazhinji zvinoenderana neakajairwa mabhodhi pasina spacing collage V-CUT, zvichikonzera hafu-gomba mhangura neV-CUT banga rakabvarura gomba rakakonzerwa pasina mhangura, chigadzirwa hachigone kushandiswa.
Semi-perforated plate kugadzira
1. Tsanangudzo yehafu-gomba ndiro
Half hole inoreva kugadzirwa kwesimbi yegomba hafu mubhodhi, hafu mubhodhi kunze, chigadzirwa chinoda buri remadziro eganda remhangura kuti richengetedzwe mudziyo maburi. Kuyerera kwemaitiro: Kuchera → kunyudzwa kwemhangura → bhodhi pamusoro peplating → denga rekunze remutsara → graphic plating → tin inotungamira → kugaya hafu yegomba → desmear → etching → desmea
2.Half urefu slot processing
Kana iyo hafu-gomba iri slot gomba, zvinodikanwa kuti uwedzere ∮ 0.8-1.1mm yekutungamira gomba kumagumo ega ega slot. Maburi egwara anofanirwa kuiswa muchikamu chechipiri chekubooresa zvakasiyana kudzivirira maburi ehafu-slot kubva mukushushikana kusina kuenzana, kuputika kweganda remhangura, uye pamberi peyakagayiwa hafu-gomba kuwedzera maitiro maviri ekubooresa.
3. Half-hole gong tepi
Iyo hafu-gomba ndiro inoda kuitwa yakavharwa furemu ine hupamhi hwe1.6mm, inonzi GKO2 (yakagayiwa hafu-gomba isati yaiswa). Ita collage, inoda kuita GKO2 (milled half-hole before etching) mukati meSET, uye nzvimbo yakavharwa haigoni kupinda mundiro, iyi poindi yakakosha zvikuru, kuitira kufambisa chimiro chekudhirowa kwehafu-gomba gong tepi kufambisa kudhirowa kwegong tepi kuti uone nzvimbo yehafu-gomba.
4. Half-hole connection
Kana iyo hafu-gomba yakaunzwa seveneer uye yakakomberedzwa nehafu-makomba, imwe neimwe yemakona mana ebhiriji inofanira kunge yakakura kupfuura 2mm kudzivirira bhodhi kuti isakanganiswe mukugadzirwa kwekugadzira. Kutenderedza hafu-gomba SET, kuwedzera maburi echitambi mumakona ebhodhi kuti abatanidze, kana makona egongo hafu-gomba bhodhi yekubatanidza isingasviki 1.6mm, hapana chikonzero chekuwedzera zvitambi. Split boards inogona kuputswa zvakananga.
5. Half-gomba, Drilling line kugadzirwa
Half-hole board drilling uye yakajairwa bhodhi kuchera kunogona kuve kwakajairwa muripo. Iyo yakaderera hafu-gomba yakapedzwa aperture ndeye 0.5mm, iyo hafu-gomba bhodhi chimiro chakajairwa kuchekwa kwemhangura, uyezve yakajairwa yakaturikidzana mapedhi, pad spacing ≥ 0.25mm, kudzivirira chigadzirwa chakapedzwa kubva pawelding kunyangwe mupfupi wedunhu.
6. Half-gomba solder kuramba kugadzirwa
Half-gomba bhodhi rakavharwa nzvimbo vanofanira kuzarura hwindo, (kana hafu-gomba bhodhi rakavharwa nzvimbo haana kuvhura hwindo kuchaita kuti hafu-gomba gomba rusvingo neingi kupinda).
Hafu-gomba inoenderana nemutsetse pakati pemapadhi haigone kuvhura hwindo, kana iwe usingakwanisi kuchengeta bhiriji inoda kusimbiswa nemutengi. Zvinokurudzirwa kushandura chinhambwe pakati pehafu-gomba, kana iwe usingakwanise kuona kuti pad spacing iri nyore kubatanidza kunyange tini.
Iyo nzira yekugadzira yehafu-gomba ndiro yakanyanya kuomarara kupfuura yakajairwa ndiro, uye mutengo wakaenzana wakakwira zvakare. Kana ukasashandisa Huaqiu DFM kuti utarise pachine nguva, zvinogona kutungamira kuverengero isiriyo yemutengo wekugadzira wechigadzirwa, uye wobva waona kuvepo kwehafu-gomba muchigadzirwa pakugadzira, izvo zvinononoka kutenderera kwekugadzirwa kwechigadzirwa cheR&D.
