Raws li peb yob mus rau xyoo kaum peb ntawm lub xyoo pua 21st, cov khoom lag luam luam tawm tau zoo tuaj yeem xaj hauv qhov me me rau tus nqi qis heev … yog tias koj tsis mob siab tos lossis nyob hauv zej zog yog. Tab sis ntau zaus kuv tsuas yog xav kom cobble ib yam dab tsi ua ke tam sim no.

Ib daim ntawv tam sim no ntawm "perfboard" rau hluav taws xob tinkering yog ob tog, hla-qhov plated, HASL ua tiav 1.6mm FR-4 iav fiber ntau ntxiv epoxy PCB. Cov khoom siv ruaj khov thiab nyuaj rau hlawv. Cov kab laug sab tau yooj yim rau cov laug thiab nyuaj rau nqa tawm ntawm lub rooj tsavxwm. Nws muaj nyob rau hauv ntau qhov project-nyiam qhov ntau thiab tsawg.

Nws kuj tseem tsis zoo rau kev txiav rau qhov loj me nrog kev ua kom huv. Ua phooj ywg zoo li nyuaj thiab txaus ntshai. Los yog kim rau cov cuab yeej uas ob peb tus neeg nyiam ua haujlwm yuav.

Nov yog qhov piv txwv tsis raug ntawm tib neeg tham txog qhov ntawd.

Qhov no 'ible piav qhia qhov yooj yim, pheej yig, nrawm thiab muaj kev phom sij txo txoj hauv kev txiav thiab ua kom huv huv ua tiav ntawm FR4 perfboard. Cov kauj ruam tiag hauv nruab nrab yog qhov yooj yim, ntxiv rau txhua lo lus no ua ntej thiab tom qab.

Khoom siv

• FR-4 perfboard / protoboard / prototype PCB-Piv txwv
• Compound / "aircraft" snips - piv txwv (US $ 4)

• Carborundum sharpening pob zeb - piv txwv (US $ 3)

  Txhim kho: pob zeb diamond - piv txwv (US $ 27)

• tub/tais loj thiab tob txaus kom npog pob zeb nrog dej
• qub txhuam hniav
• ntawv/phuam pov tseg

Kauj Ruam 1: Um, Kev phom sij?

Cov iav feem ntau tsis muaj mob. Tab sis fraying lossis sib tsoo cov iav iav ua rau plua plav uas tsawg kawg ua rau khaus thiab tuaj yeem ua rau tsis zoo. Yog li kuv yuav tsis ua pa lossis faib cov hmoov av. Thiab zam kom tsis txhob muaj plua plav pab ua kom txoj haujlwm yooj yim.

Cov hmoov txhuas yog cov tshuaj lom ua kom muaj kab mob hauv lub cev. Tsis txhob noj nws. Tsis txhob faib nws mus rau ib puag ncig. Lwm yam

Cia peb xav tias qhov ua kom tiav cov hlau nplaum muaj cov hlau lead. Hauv kev saib nrawm Kuv tsis pom ib tus neeg muag khoom tshaj tawm cov laug cam no raws li RoHS lossis "tsis pub dawb". Cov laug cam uas kuv tau tso tseg cov cim xim-xim uas txhuam rau ntawm daim ntawv dawb.

Tua me ntsis cov hmoov txhuas thiab sib tsoo txhuas ua hmoov av ntawm koj cov ntiv tes niaj hnub no tuaj yeem mus tsis zoo tom qab.

Yog li rau qhov no: ible:

• siv kev saib xyuas tsim nyog nrog txiav thiab hnav khaub ncaws tshiab txiav cov ntug
• zom hauv dej
• ntxuav koj txhais tes (Kuv tej zaum yuav tsum hais tias "hnav hnab looj tes")

Nco ntsoov qhov no tsuas yog qee qhov kev tsis tsim nyog ntawm tus tsav tsheb uas koj pom ntawm Teh Interwebz. Ntseeg ib yam ntawm nws yog ntawm koj.

Kauj ruam 2: Teeb

Nrhiav qhov chaw ua haujlwm uas yog

• yooj yim los so (tawv, tsis ntxeem tau, tsis nqus)
• qhov twg koj tsis tuav zaub mov.

Teem koj lub pob zeb sib tsoo hauv lub tais/tub/ntim thiab ntim nrog dej txaus los npog lub pob zeb.

Kauj ruam 3: Txiav

Cov snips yooj yim txiav raws txoj kab ntawm qhov.

Cov npoo yuav me ntsis ntxhib nrog cov iav tawg thiab tawg ntawm cov phaj hlau npaj kom tawg. Kev txhuam nrawm ntawm lub pob zeb yuav tshem tawm cov khoom uas yuav poob los ntawm lwm yam. So cov hnoos qeev thiab so cov khib nyiab nrog qee yam zoo li daim ntaub ntub dej. Khaws cov khoom seem hauv lub hnab lossis ntim khoom vim tias lawv tseem muaj ntau qhov ntxhib txiav plating cov khoom uas yuav tawg nrog ib qho tseem ceeb tuav.

Rau daim uas koj yuav ua tiav thiab siv, txuas ntxiv mus ntxuav cov npoo kom huv si …

Kauj Ruam 4: Sib Tsoo Edges Ca

Tuav lub pob zeb hauv qab dej, zom cov plated seem ib nrab qhov.

Zuaj nrog quab yuam kom txiav sai dua, koj tsis zoo li yuav tawg pawg thawj coj.

Kauj ruam 5: Chamfer

Tshem tawm qhov me me ntawm cov ntaub qhwv uas tsis muaj zog uas tuaj yeem tawm ntawm lub ntsej muag ntawm daim.

Kauj Ruam 6: Ntxuav

Cov dej yuav ua kua mis nrog cov hmoov av uas koj tsis ua pa thiab lub pob zeb yuav tuav qee cov phaj.

Txheeb cov phaj tawg tawm ntawm lub pob zeb, hauv dej, nrog tus txhuam hniav qub. Yaug lub pob zeb thiab muab tso rau ib sab kom qhuav.

Cia cov dej hauv tus tub sawv ntsug tsis muaj kev cuam tshuam ib pliag.

Tom qab cov hlau hais haum, ua tib zoo nchuav cov dej pov tseg tawm hauv av hlau hauv qab ntawm tus tub. So cov hmoov av uas ntub nrog me ntsis ntawv phuam. Muab cov ntawv coj los pov tseg thiab ib daim PCB uas koj yuav tsis khaws rau hauv ib cheeb tsam uas tsim nyog uas yuav tsis tawg.

Ntxuav lub dab da dej thiab tsis txhob siv nws ua zaub mov noj.

Ntxuav koj ob txhais tes.

Kauj Ruam 7: Ua Koj Li

Koj qhov khoom yuav yog koj tus kheej. Tshwj tsis yog tias koj ua ib qho ntawm cov no.

Kauj Ruam 8: Ntawm Cov Cuab Yeej

Yooj yim (tsis yog sib xyaw/aviation) tin snips yuav ua haujlwm zoo. Los yog cov no

Sib nrug los ntawm kev sau qhov no 'ible, Kuv siv pob zeb diamond hone zoo ib yam li piv txwv nyob hauv Cov Khoom Siv Khoom (qhov no. Uas zoo li yuav tsum tau txiav). Qhov ntawd ua haujlwm zoo tab sis tsis haum rau tus ntsuj plig ntawm qhov no. Txhawm rau sau qhov no, kuv sim pob zeb carborundum rau qhov piv txwv yees duab. Nws ua haujlwm zoo txaus. Xav txog tus nqi qis thiab muaj dav, uas ua rau muaj kev nkag siab zoo rau qhov kev mus-yuav-uas-ua-ua-cov ntsiab lus no. Kuv xav paub tias qhov no US $ 10 HF pob zeb diamond hone teeb yuav ua li cas.

Tej zaum koj twb muaj pob zeb ntxhib ntxhib. Yog tias muaj, nws yuav raug thauj nrog roj. Kuv tsis paub tias ua tau zoo lossis tsis zoo uas yuav ua haujlwm zoo - rau PCB, rau pob zeb lossis rau kev ntxuav. Tej zaum lub pob zeb tshiab, tsis tau roj, yuav ua haujlwm zoo dua li pob zeb roj.

Kauj Ruam 9: Ntawm Txuag Txhua Yam

Kuv khaws txhua daim me me uas tseem tshuav. Daim duab qhia pom kuv cov nyiaj khaws cia tam sim no, uas tau txais nyias - pov thawj tias ob peb lub perfboard kawg dhau los tau siv cov seem ntau dua li ua ntau dua.

Cov chips me me tuaj yeem zoo li ua tsis zoo, tab sis cov piv txwv sau hauv Kev Taw Qhia suav nrog ob peb ua nrog cov khoom me me zoo li ntawd. Tsawg kawg yog ib qho piv txwv me me uas haum rau ib qho ntawm cov khoom seem uas twb muaj lawm hauv tes.

Qee lub sijhawm kuv xav tias tej zaum kuv vwm me ntsis kom khaws cov khoom tawg. Thaum kuv xav xaim lub tso suab tso suab rau peb lub davhlau ya nyob twg hauv daim duab thiab pom cov khoom seem raws qhov loj me, kuv tsis txhob txhawj txog qhov ntawd. (pom tseeb kuv tsis thab nrog tu cov ntug ntawm daim ntawd)

Kauj ruam 10:… thiab Qee Cov Lus Cim Ntxiv

… Lossis txiav luam yeeb thiab mus ua ib yam dab tsi.

… Tseem nyeem?

… Vim li cas?

… Ok…

Cov qhab nia & tawg yog lwm txoj hauv kev los txiav PCB tsis muaj cov cuab yeej tshwj xeeb. Yog:

• txhua qhov tawg mus rau txhua txoj kev hla cov khoom tawg nws ua ob daim - tsis muaj cov ces kaum sab hauv
• muaj cov khoom txaus los tuav lossis clamp ntawm ob sab ntawm qhov tawg - nyuaj ua kom tawg tawm me me/luv luv

1.6mm FR4 xav tau kev pov npav thiab ua txhaum.

Nrog cov laug cam no kuv tuaj yeem tau qhab nia thiab tau txais kev so kom huv raws cov khoom ruaj khov ntawm kab, khaws tag nrho cov plated los ntawm qhov ntawm ob sab ntawm kev so tsis txhob nkim kab. Sib nrug los ntawm qee qhov laj thawj vim li cas koj thiaj tsis tuaj yeem muab pov tseg ib kab ntawm qhov, nws tsis nyob qhov twg ze qhov tsim nyog thab.

Koj yuav tau pom qee qhov hauv qab 0.1 "ntu hauv thawj daim duab. SOIC, SOT23 & lwm yam SMT kev dag tau tawm ntawm qhov no rau ible tab sis tuaj yeem tsim ib qho ntxiv ible hnub ntxiv.
