Solder rosin: vamwe pokunamatidza zvakavanzika

Mumwe redhiyo mudzidzi kana tenzi, nevanhu kugadziriswa pachako, pakupedzisira, achafanira kuti atore pokunamatidza simbi uye wekuedza. Quality basa, uye kunyange kuita zvinhu zvichaita kuvimba zvinhu zvakawanda, izvo vanoziva kudiwa nechokwadi asati atanga basa zvakananga.

Rairira basa ane pokunamatidza simbi

Pasinei sokuti nyore basa pokunamatidza simbi, zviri anodiwa kwazvo kuva dzinokosha unyanzvi yepamusoro basa uye kukwanisa zvakanaka kushandisa solder pamwe rosin.

Pokunamatidza rinoitwa kushandisa dzakasiyana-siyana solders. Vanonzi solder ari Coil pamwe rosin, zvichida kupfuura mukurumbira. Kana achiita basa chokuita pokunamatidza solder inoshandiswa. Nhamba raiva kutungamirira uye gaba - 60 uye 40%, ukuwo. chiwanikwa ichi inonyunguduka pa 180 c.

Unofanira kushanda pamwe pokunamatidza nedare:

• pokunamatidza simbi pachayo;
• solder;
• rosin.

The nenharo solder pave yakakwana interconnection pamwe simbi akadai mhangura, ndarira, sirivha, nezvimwewo, kana zvinotevera ezvinhu ..:

• Hukawanika zvikamu zvinofanira kucheneswa kubva oxides.
• Detail of nenharo panzvimbo pokunamatidza hwakasimba utsotso tembiricha yacho solder.
• Panguva pokunamatidza kushanda kunodiwa kudzivirira pamigumisiro okisijeni, zvakasiyana-siyana fluxes anoshandiswa. Unhu rwokudzivirira firimu zvakananga pamusoro pokunamatidza panzvimbo.

Book sei solder, unogona kuverenga uye kunzwisisa, asi pokunamatidza unyanzvi kunogona kuwanika uchidzidzira.

Mazano uye zvakavanzika anoshanda pokunamatidza simbi

Mushure solder yakatanga kunyunguduka, atova zvinogoneka solder. Nokuti ichi zvakafanira kufukidza pokunamatidza muromo netolstym solder rukoko uye ipapo kwazvo dziome pamusoro nyoro chipanji. Saka bvisa Zvakasara basa solder pamwe rosin. Zvinokurudzirwa kuti mune tsika vachidzipukuta rumborera nyoro chipanji pashure mumwe pokunamatidza.

Usati watanga solder redhiyo zvinoriumba, zvakafanira kugadzirira. It apfugame ayo paMharidzo kuitira kuti chikamu akasununguka kupinda buri aida nokuti.

Vatsva pasina ruzivo kazhinji chokuita pokunamatidza muromo pokunamatidza muromo. A vanofanira kuchengeta pokunamatidza simbi kuitira kuti pakati pake panzvimbo pokunamatidza nokudyidzana nzvimbo kwakaenzana zvichibvira, kana zvikasadaro nzvimbo kubereka solder iri huru zvokuti noukama zvikamu.

How kuchenesa pokunamatidza muromo

Kana pokunamatidza pokunamatidza simbi kazhinji anooneka Nagar. Inogona kubviswa pamwe pachena mvura. Kana ukabata pokunamatidza simbi pamusoro nyorova jira, ipapo pakafunuka zvichava pairi, uye kuruma zvakare ava akachena. Nguva nenguva unofanira ichi chakaitwa paunenge uchishanda pokunamatidza simbi. Kana jira hakuiti kubatsira, unogona kushandisa zvakaoma chipanji.

Classes pokunamatidza muromo

• Pokunamatidza bvisika pamwe nickel unhani.
• I dzinopfonda mhangura.

Pokunamatidza yezasi mukirasi okutanga yemanyorero kushandiswa solders yakaoma, izvo anokwanisa waidzora tembiricha.

Zvatopera rechipiri - rakajairika.

Types kuifukidza pokunamatidza muromo

• The Rumborera muchimiro tsono - vane vashomashoma solder redhiyo zvinoriumba akadai SMD. Mune Implementation zviri kugadziriswa hunokosha ruma dzeserura. Rinoshandiswa pamusoro mapuranga yakakwirira arambe achirema pamusoro vakatasva zvikamu.
• Kuruma-spatula - inoshandiswa nokudiridza uye panyaya kugadzwa guru zvemagetsi zvinoriumba. Vari kushanda multi-kutungamirira chip.
• The Rumborera ari muchimiro samadonhwe - zviri nyore kutakura solder pamwe rosin kunzvimbo pokunamatidza zvichiguma dzakakwirira huri basa.
• Kuruma ane curved fomu - kazhinji ivo desoldering redhiyo yaiva yemhangura goko kuti bhodhi haina kugara imwe solder. It rinogona kushandiswa kwakajairika pokunamatidza. A pokunamatidza simbi neshungu kuti tembiricha kuti 290-300 C.

Nokushanda pamwe pokunamatidza simbi, unofanira kugara nayo yakakwana utsanana. The itsva pokunamatidza muromo inowanzopiwa kubatwa nenyundo wayo pamusoro vakaumba neminzwa diki. Naizvozvo, avo neatly kupetura aine faira kupa kupfuura kwakarurama chimiro rumborera.

Ipapo Rumborera vanofanira zaludit uchishandisa solder pamwe rosin. Kureva, nhete paiva solder kuombekwa ndokuita nebwe.

How muchitonhorera pokunamatidza nzvimbo

Forceps nesimbi, vanoomerera redhiyo zvinoriumba, uye richiri kushanda sechinhu kupisa singi panguva pokunamatidza. Unogona kushandisa iyi chinangwa uye rinokosha kiramba "garwe".

Zvakavanzika pokunamatidza pokunamatidza simbi

Kuti vawane mugumisiro wakanaka kana pokunamatidza kunodiwa kuti zvakakodzera kushandisa solder pamwe rosin uye zvinoyerera. Ichi chaiwo yakaderera-kubvunda simbi chiwanikwa, izvo solder zviteshi zvikamu uye waya.

• Best solder - gaba iri yakachena chimiro. Asi simbi iri kudhura kurishandisa panguva pokunamatidza. Naizvozvo, kana tichishanda redhiyo hurongwa anoshandiswa inonzi vatungamirire-gaba solders.
• Nomutobvu netini. On simba izvi brazing solders nani pane yakaisvonaka gaba. Vari vavhunduka imwe tembiricha kuti 170-190 inegumi. Kureva solders dzakadaro chidimbu "Pos" - gaba-kutungamirira solder. Ndakamira pashure tsamba idzi vari pakunzi nhamba zvinoreva nhamba netini, vakaratidza kuva chikamu. Zviri nani kushandisa solder "Pos-6D".

• Fluxes - ndiwo zvinhu izvo nhaka antioxidant ehupfumi. Ivo zvinoshandiswa kudzivirira oxidation yacho solder mapfundo. Kana musingadi kushandisa ane zvinoyerera, kuti solder haangopi kuomerera pechiso simbi.

Mhando achichinja

Kana kushanda redhiyo zvinoriumba vaishandisa fluxes zvisingakwanisi ane acid. Somuenzaniso, rosin. The zvitoro dzinotengeswa Rerekera rosin nokuda lubrication zvemimhanzi. Zvingangodarowo kushandiswa pokunamatidza. Asi simbi midziyo soldered uchishandisa rosin-isina solder. Nokuti ronda raro waida "Rework asidhi". Izvi zvazvichanyungudutswa hydrochloric asidhi uye zinc. Electronic pokunamatidza pamwe solder saizvozvowo hazvibviri, nekuti pakupedzisira achaparadza brazing.

Kana uchida kuita solder munzvimbo dzisingasvikiki, zvinokosha kuva mvura nekubudisa. Chinogona kuitwa tisingatungamirirwi. Rosin huchaparadzwa zvikaita guruva, izvozvo yakadururirwa acetone kana ethyl doro. A akamutsa mhinduro vanofanira kudira zvakawanda rosin kusvikira gobvu pasty guru. In panzvimbo pokunamatidza imvura nebwe kuiswa aine mumakwenzi kana tsvimbo. Muchiitiko chino, pane nuance - nokuti vakaongorora akadhindwa redunhu mapuranga nekubudisa inofanira kupfuura mvura. Nokuti nesimba kusvika nzvimbo, unogona kushandisa solder waya pamwe rosin, riri zvikuru yamunenge.

Kana tichishanda fluxes siyana zvinofanira kukurukurwa kuti avo kuti akaumbwa acetone, - muchetura kwazvo. Saka, kushanda navo kudzivisa utsi inhalation. Plumbing nani pedo pahwindo, kana muzhizha, uye muchando kazhinji fefetedza mukamuri umo basa rinoitwa. Paunenge wapedza kuva nechokwadi kuti maoko ako nesipo nemvura inodziya.

Sei solder solder pamwe rosin

An chinokosha zvimiso pokunamatidza ndiko kubudirira uye kuchena hukawanika kuti vanofanira solder. Iva nechokwadi kuti solder majoini yakachena chivheneke. mashoko ipapo unofanira kupfeka nhindi rosin uye kudziya. The yakaumbwa rosin solder achatambanudza zvakaenzana pamusoro guidewire kana mashoko uchida solder. Zvinokwanisika zvakarurama tenderera ari chinhu, kumhanya pamusoro paro pokunamatidza simbi kuti solder yakafukidza zvakaenzana mhiri pemvura.

Kana zvakakodzera zaludit kondakita riri soldered kuti puranga, pashure nokutorera nzvimbo pokunamatidza pamwe sandpaper kana banga zvakafanira kuuya chimedu rosin, uye ipapo solder zvakanaka kuparadzira sezvo zvakaenzana sezvinobvira, vachipedza pokunamatidza.

At pokunamatidza kunzwisisa sei uye tsime sei zvakabatana nokuda pokunamatidza waya kana vokukurukura mashoko. Vanofanira kuva zvakasimba akavanyengetedza pamwechete, uye ipapo akagadzirira kuuya pokunamatidza conductors maererano nayo. Mushure nenharo solder vachaparadzirwa kwose pamusoro penyika, Gulf kunyange Makwanza duku pakati pavo, mumwe pokunamatidza simbi anofanira kubviswa.

kuramba pokunamatidza nguva Hachifaniri kupfuura kwemasekonzi mashanu. Shure kwenguva ino, solder solidifies uye mashoko uchasimbiswa waakaita. Zvisinei, kuti varege kuparadza pokunamatidza nhengo risingazununguswi mukati 10-15 masekonzi pashure pokunamatidza kuvhara. Zvikasadaro, kubatana ndiro kugadzikana.

Kana uri kushanda pamwe transistors, avo vawana inofanira kuchengetedzwa kudzivirira overheating. Zviri nani kuti varambe kana pingisi kana tweezers, kuita izvi kupisa nounzenza.

Kana pokunamatidza zvigadzirwa zvinoriumba chero zvazvingava hazvina zvakakodzera kuti kumonyanisa kumigumo zvikamu. Kana uchida solder zvikamu kana kutsiva conductors, zvinokosha kufunga pachine nezvazvo asati installation. Kumigumo dzakawanda akarurama pokunamatidza nechokure diki kubva mumwe, pane nzvimbo imwe.
