Luti luso: kupanga matabwa kusindikizidwa dera

Kuti pakhale Luti (laser luso chitsulo)? Izi ndikuuzani nkhani yathu.

matabwa Kusindikizidwa Dera

Ntchito yomanga zamakono kumagwirizana ndi chilengedwe cha matabwa kusindikizidwa dera. Ngati simukufuna kuti kuwononga nthawi kupanga awo, njira anafotokoza m'nkhani ino ndi abwino kwa inu. Pamaso pa luso chokwanira Iye adzalola mfundo kuti magawowa zilandiridwenso. luso Luti akhoza kugawidwa mu magawo zotsatirazi kupanga PCB ndi:

1. Pangani zojambula.
2. Kupanga workpiece.
3. Ife kusamutsa chitsanzo ake.
4. Grass workpiece.
5. Chitakonzedwa.
6. Porting kuchita.
7. Tinning bolodi.

Monga mungaonere mchitidwe Luti luso kunyumba akhoza akuyendera popanda mavuto aakulu ndi ndalama. Mwina ngakhale kupeza chilichonse chatsopano, chifukwa zonse muyenera kugwira ntchito mosavuta opezeka chipinda zofunikira. Luti luso kusindikizidwa matabwa dera bwino wosakanikirana milandu komwe kuli Mlengi limodzi la zamagetsi ndi fani umodzi. Ponena za ubwino, choyamba taganizirani za cheapness, kudalirika ndi chomasuka ntchito. Ndithudi, izo si ubwino onse ndi tatchulazi ziri zoposa mokwanira, kuti athandize umisiri Luti ofotokoza anasankha, amisiri ambiri m'banja.

kulenga zojambula

Pali zipangizo zosiyanasiyana: kuchokera pensulo zochitika zapadera. Pamene munakonza komiti dera ayenera kuyesa kukwaniritsa zolinga izi:

1. Kuchepetsa chiwerengero cha jumpers.
2. Track wachibale wina ndi mzake ayenera udzakhazikitsidwe mosamalitsa perpendicular ndi kufanana.
3. Yaying'ono unsembe.

Pa chilengedwe zithunzi, kuganizira miyeso ya zinthu, mbali pini ndi makulidwe awo. Komanso, chisamaliro ayenera kumwedwa mkulu-panopa ochititsa ndi njanji onse. Kupanga chitsanzo angayerekezedwe masewera a Tetris: inu mukhoza kulemba zinthu monga adakondweretsa, mpaka amalandira abwino amene angathandize kumasulira mu luso zenizeni Luti. Inkjet chosindikizira (kapena laser) kudzakuthandizani kukhala iyo kukhudza thupi ndi manja awo.

Kupanga akusowekapo

Choncho kuzilingalira tili, ndipo ife tikhoza kulankhula za ndalama ndi. Tsopano muyenera kuzilingalira odulidwa, kuvala PCB ndi kubwezeretsa ndi mtsogoleri. Ngakhale si choncho zovuta Luti luso? Zojambulazo, ndicho chimene tiyenera! Dulani mizere pa preform PCB zojambulazo. Flatten kukafika kutsogolo m'mbali ndi wapamwamba ndipo amachita chithandizo pamwamba. Kuti tichite zimenezi, mukhoza kugwiritsa ntchito yabwino grater nazhdachku kapena waya (anthu amene kuyeretsa mbale), pamodzi ndi kusamba madzi.

Kusamutsa fano: mwachidule

Tiyeni tiyerekeze kuti tinasindikiza chifanizirocho osindikizira laser. Ndipo tiyenera tsopano kusuntha kwa akusowekapo ndi pepala. Tsatirani zimene zinachitika chifaniziro cha zojambulazo pa. Wogawana kusita chitsulo, koma ntchito kokha khama pang'ono. Paper ndi katungulume kutali, Richt ndi zitsamba. Ngati inu kusindikiza zojambula, ndi zofunika kukhala kuwala osachepera kuti fano mdima kwambiri. Ndi zofunika kuti aonetse ndi osalimba mkulu wa tona m'malo ena. Izi ndi zofunika kupewa mavuto kwa lumens, kumene tsoka, ali ndi luso Luti. Kukula osachepera mipata ndi wolandiridwa, ndi zofunika kuti sali wamkulu kuposa 0.2 millimeter.

Kusamutsa zojambula: pepala

Ndi chinthu chabwino, kotero kuti sanasankhe ayenera kulankhula mosamala. Kodi zitsanzo za bwino Muwona Luti luso? Pepala ayenera wandiweyani, n'zotheka kutenga lokutidwa. zala aliwonse musakhudze. Muyenera kugula mapepala lokutidwa - mukhoza kutenga ukukamba. Chinthu chachikulu kuti iye ali mbali imodzi kunali woyera. Mulimonsemo, bwino katundu ndi mabuku awiri a matabwa kusindikizidwa dera. Dulani ndi superimpose pa workpiece kuti chitsanzo anali ndi zojambulazo lapansi. Kutenga chitsulo wamba, musagwiritsire ntchito mpweya wotentha. Kutentha ndi bwino kuika pafupifupi. Chimatsatira mbali ya chithunzi, kuti si atavula kwa workpiece lapansi. Yambani pang'onopang'ono kusalaza fano, koma musalole kuloza. Komanso, musati overdo ndi mphamvu ngati atolankhani ndi amphamvu kwambiri, tona ndi kupaka, ndi kuti m'mabande. Ichinso angagwe ngati chitsulo ndi kotentha. Ngati mwakhala zoipa ankachitira workpiece m'mphepete, inu sadzatha kutsegula tona ndi zabwino kwa iye. Pamene chirichonse chiri chokonzeka, ndi workpiece kukhala ozizira. Kenako mu mbale ndi madzi ofunda. Kuwonjezera supuni asidi acetic. Paper kumafeŵetsa ndipo akuyamba kuwira. mphindi khumi lidzagwa kumbuyo tona lapansi. Chithunzi chifukwa, kusamba bwino ndi madzi. Choyamba, kupunduka akhoza kukhala, koma pa achiwiri wa kuyesera ayenera kukhala zokwanira kuzipewa. Ukadaulo ambiri Luti PCB kupanga tingaone m'malo yovuta, koma si poyamba. Mwa njira, nkhani pamwamba analimbikitsa kuti ndikhale ndi mapepala awiri, ndipo zimenezi sizinachitike mwangozi. Pa kulowa choyamba, oyamba ambiri amalakwitsa pang'ono kuti kutembenukira topaka tona ndi missteps ena. Ku dera bolodi kusindikizidwa adzapeza bwino, ndipo analimbikitsa kukonza tayala yopuma.

Kodi ngati pali chosindikizira laser?

Mukhoza kugwiritsa ntchito pentopeni okhazikika. Komanso abwino Mwaichi, ndi msomali osalala, ntchito burashi woonda. Ambiri akhoza ntchito pensulo osachepera limodzi ndi chofufutira. Izo ntchito mu sayansi milandu Luti ndi ntchito ulimbo zotsatira bwino. Pamene inu kutsuka zotsala za madzi, onetsetsani ziri wapita. Komanso, pamene inu kubowola maenje, onetsetsani kuti mfundo iwo adzamvera bwino.

kukolola udzu

Iwo amagwiritsa mankhwala enaake ferric. Pamene kugula wothandizira, onetsetsani kuti umakhala ufa. Izi mankhwala enaake ferric ndi abwino kwambiri zolinga zathu. Ngakhale kuti si lilibe, ndipo asankhe ntchito osakaniza sodium kolorayidi ndi sulphate mkuwa. Koma apa m'pofunika kukhala kufanana ena. Choncho, pa lita imodzi ya madzi owiritsa muyenera magalamu mazana awiri vitriol ndi kuwonjezera tebulo mchere mpaka si kupasuka. Yankho chifukwa kunali kofunika zosefera. Ngati usavutike kutentha madigiri 50 Celsius, kufunika etching mkuwa mphindi 15-20. Koma kumbuyo kwa mankhwala enaake ferric. M'pofunika mudzaze thanki ndi madzi ndi kuwonjezera etching chikuchitidwa teaspoons wa mankhwala enaake ferric. Samalani, chifukwa mankhwala anachita zimene zimachitika kukhala kwambiri kupanga kutentha ndi njira chifukwa akhoza sprayed ngakhale pang'ono. Chirichonse bwino wothira. Gwirani chala chanu njira ndi kuonetsetsa si kotentha. Kenako ikani workpiece mmenemo, makamaka angalepheretse pansi - kuti yankholo padziko. Choyamba, kungakupatseni tiwolokere ndi zitsamba. Pa nthawi, idzatitimira. Ndiyeno nkutembenuka pa PCB zojambulazo ndi kuika mu njira. Nthawi mphamvu zofunika kugwedeza iye, kuti rinsed padziko mkuwa kusungunuka. Ngati thovu kuoneka, m'pofunika kuchotsa bolodi, kusamba, ndipo kupitiriza etching. Malinga ndi kutentha njira ndi ndende zake, ndondomeko imeneyi angachite kuti 1 ora.

Lambulani preform ku tona ndi

Tsopano takumana ndi vuto wa chiyero. Pali njira yapadera zimenezi, koma iwo sakupeza ndemanga zabwino ndipo anthu ambiri amakonda njira makina a kuchotsa tona. Ndi bwino kugwiritsa ntchito waya zimatengedwa osamba mbale, amene angapereke chifukwa yabwino.
