Farerne ved bly<\/h2>\n\n\n\n

Bly har v\u00e6ret brugt i forskellige industrier i over tusind \u00e5r. Det bruges ogs\u00e5 i produktionen af PCB-kort (Printed Circuit Board)<\/a>. I \u00f8jeblikket er det globale \u00e5rlige forbrug af bly ca. 5 millioner tons. Heraf bruges 81% i batterier. De n\u00e6stst\u00f8rste anvendelser er i hvid blyoxidmaling og v\u00e5ben, som hver tegner sig for omkring 10%. Disse tre er de vigtigste destinationer for store m\u00e6ngder bly. Faktisk er den m\u00e6ngde, der bruges i printkortproduktion og loddeindustrien til elektroniske produkter, kun 0,49%. Men fordi det er spredt over s\u00e5 stort et omr\u00e5de og er meget vanskeligt at genanvende og genbruge, kan den forurening og skade, det for\u00e5rsager, ikke betragtes som mindre. Farerne ved bly er tydelige ud fra dette.<\/p>\n\n\n\n

Blykoncentration i blodet vs. sundhedsp\u00e5virkning<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Bly er en \u201cdr\u00e6ber\u201d af celler. N\u00e5r blykoncentrationen i blodet n\u00e5r op p\u00e5 15 mg pr. 100 ml, kan det for\u00e5rsage forsinket udvikling og nedsat intelligens hos b\u00f8rn. Desuden er nerveskaderne mere alvorlige, jo yngre barnet er. Blyforgiftning viser sig som overdreven bev\u00e6gelse, ophidselse, d\u00e5rlig s\u00f8vn, appetitl\u00f8shed, hyppig vandladning eller sengev\u00e6dning, irritabilitet, hum\u00f8rsvingninger og endda d\u00e5rlig h\u00f8relse og sproglige udtryksevner. Farerne ved bly er meget forf\u00e6rdelige, s\u00e5 det haster med at skifte til blyfri produktion i printkortproduktionen.<\/p>\n\n\n\n

Farerne ved bly i PCBA-blod<\/h2>\n\n\n\n

Blyforbindelser siver let ned i grundvandet, hvilket bliver en potentiel krise for drikkevandet. Tag Japan som eksempel: landets milj\u00f8beskyttelsesregler kr\u00e6ver, at bly i grundvandet ikke m\u00e5 overstige 0,3 ppm (0,3 mg\/l). I USA er gr\u00e6nsen for bly i drikkevand i EPA 40 CFR 141 endnu strengere med en \u00f8vre gr\u00e6nse p\u00e5 kun 15 ppb (0,015 mg\/l). If\u00f8lge TCLP-toksicitetsudvaskningstesten i U.S. Environmental Protection Agency's EPA 40 CFR 261 m\u00e5 den maksimale udvaskbare m\u00e6ngde bly kun v\u00e6re 5 mg\/l. Men den m\u00e6ngde bly, der udvaskes fra forskellige lodninger i den almindelige printpladeproduktion, n\u00e5r de kasseres i naturen, er hundredvis af gange h\u00f8jere end udvaskningsm\u00e6ngden i ovenst\u00e5ende test. Faren ved bly er s\u00e5 stor - hvordan kan det undg\u00e5 at g\u00f8re folk forsigtige og bange? Derfor er skiftet til blyfri produktion i fremstillingen af printplader til elektroniske produkter bydende n\u00f8dvendigt.<\/p>\n\n\n\n

Bly og blyfri lodning i PCB-produktion<\/h2>\n\n\n\n

Blylod (ogs\u00e5 kendt som SnPb-lod) er en metallegering med bly (Pb i det periodiske system) og tin (Sn i det periodiske system) som de grundl\u00e6ggende komponenter. For mange \u00e5r siden blev brugen af blyr\u00f8r og alle vandforsyningsr\u00f8r, der var forbundet med blylod, forbudt i nye amerikanske vvs-systemer. Kort tid efter blev de arbejdsm\u00e6ssige risici ved blylodning ogs\u00e5 overvejet, og blybaseret lodning blev en dokumenteret sundhedsfare p\u00e5 arbejdspladsen. Det st\u00f8v og de dampe, der opst\u00e5r ved lodning med bly, anses for at v\u00e6re giftige ved ind\u00e5nding.<\/p>\n\n\n\n

Derfor forts\u00e6tter udfasningen af blyloddet p\u00e5 grund af dets negative indvirkning p\u00e5 milj\u00f8 og sundhed. Blyfri loddetin er en erstatning for de traditionelle 60\/40 og 63\/37 SnPb-loddetin. I 2006 vedtog Den Europ\u00e6iske Union (EU) RoHS-direktivet (Restriction of Hazardous Substances). USA fulgte efter og tilb\u00f8d skattelettelser til alle virksomheder, der reducerede brugen af blybaseret loddetin. Nutidens blyfri loddeformuleringer har forskellige procentdele af f\u00f8lgende:<\/p>\n\n\n\n

Almindelige blyfri loddekomponenter<\/h3>\n\n\n\n
    \n
  • Kobber (Cu)<\/li>\n\n\n\n
  • Tin (Sn) - prim\u00e6r komponent<\/li>\n\n\n\n
  • S\u00f8lv (Ag) - Forbedrer styrken<\/li>\n\n\n\n
  • Nikkel (Ni) - Forbedrer holdbarheden<\/li>\n\n\n\n
  • Zink (Zn) - Hj\u00e6lper med flowet<\/li>\n\n\n\n
  • Bismuth (Bi) - s\u00e6nker smeltepunktet<\/li>\n\n\n\n
  • Antimon (Sb) - \u00d8ger h\u00e5rdheden<\/li>\n<\/ul>\n\n\n\n

    Vigtige datoer for overholdelse af RoHS<\/h3>\n\n\n\n
      \n
    • 12006 - EU RoHS 1 tr\u00e6der i kraft<\/li>\n\n\n\n
    • 22011 - F\u00f8rste st\u00f8rre RoHS-revision<\/li>\n\n\n\n
    • 32019 - RoHS 2 h\u00e5ndh\u00e6velse\u5f3a<\/li>\n\n\n\n
    • 42021 - Den globale udbredelse overstiger 85%<\/li>\n<\/ul>\n\n\n\n

      Det ultimative m\u00e5l er at v\u00e6lge loddelegeringer af h\u00f8j kvalitet, som i kombination med andre spormetaller vil opn\u00e5 fremragende mekaniske egenskaber.<\/p>\n\n\n\n

      Sammenligning af bly og blyfri loddepasta<\/h2>\n\n\n\n

      N\u00e5r man ser p\u00e5 loddetemperaturer, afh\u00e6nger det af legeringskombinationen og kvaliteten. Men generelt bliver 60\/40 tin\/bly-loddet flydende ved 361\u00b0F. Jo h\u00f8jere tinindhold, jo h\u00f8jere smeltepunkt og jo h\u00f8jere produktomkostninger. Bly-tin-lodder er nemmere at bruge; de flyder godt og kan n\u00e5 arbejdstemperaturer hurtigere.<\/p>\n\n\n\n

      Med hensyn til sikkerhed indeb\u00e6rer blyholdigt loddemateriale dog betydelige risici og m\u00e5 kun bruges, hvis det er tilladt af myndighederne. De skal ogs\u00e5 bortskaffes korrekt. Bly er skadeligt for milj\u00f8et, giftigt for kroppen, og der er risiko for, at det hurtigt optages i blodet.<\/p>\n\n\n\n

      Blyfri loddepasta smelter ved en h\u00f8jere temperatur, omkring 422\u00b0F. Selv om h\u00f8jere temperaturer kr\u00e6ver \u00e6ndringer i loddemetoderne, har samlinger loddet med blyfri loddepasta vist sig at v\u00e6re p\u00e5lidelige.<\/p>\n\n\n\n

      Fordi blyfri loddepasta har d\u00e5rligere befugtningsevne end blyholdigt loddetin, vil loddesamlingernes udseende v\u00e6re anderledes.<\/p>\n\n\n\n

      Er dit printkort lavet med en blyfri proces? Hvordan kan man se det?<\/h2>\n\n\n\n

      PCBASAIL har l\u00e6nge kraftigt anbefalet blyfri printplader for at sikre produktionen af gr\u00f8nne produkter. Hvad er det egentlig, der g\u00f8r et printkort blyfrit, og hvordan kan vi se, om et printkort er fremstillet i en blyfri proces?<\/p>\n\n\n\n

      Kontrol af udseende<\/h3>\n\n\n\n

      Blyholdigt loddetin har en lysende hvid overflade. Blyfrit loddetin ser lysegult ud p\u00e5 grund af dets kobberindhold. Denne farveforskel er en af de nemmeste m\u00e5der at skelne mellem de to p\u00e5.<\/p>\n\n\n\n

      Ber\u00f8ringstest<\/h3>\n\n\n\n

      Gnid fingeren hen over loddet: Blyfri loddetin efterlader et lysegult m\u00e6rke, mens blyholdigt loddetin efterlader et sort m\u00e6rke. Vask altid h\u00e6nder efter denne test.<\/p>\n\n\n\n

      Analyse af sammens\u00e6tning<\/h3>\n\n\n\n

      Blyholdigt loddetin indeholder tin og bly. Blyfrit loddetin har < 500 PPM bly, med hovedkomponenter som tin, s\u00f8lv eller kobber. \u201cBlyfri\u201d betyder sporm\u00e6ngder, ikke nul.<\/p>\n\n\n\n

      Matchning af brug<\/h3>\n\n\n\n

      Blyholdigt loddetin bruges sammen med blyholdige komponenter og v\u00e6rkt\u00f8jer. Blyfri processer kr\u00e6ver kompatible blyfri komponenter for at opretholde overensstemmelse.<\/p>\n\n\n\n

      Fra et brugsperspektiv bruges blyholdigt loddetin til lodning af blyholdige produkter, og de anvendte v\u00e6rkt\u00f8jer og komponenter er alle blyholdige. Med indf\u00f8relsen af disse aspekter kan du tydeligt og hurtigt identificere, om et PCBA-kort bruger blyfri lodning, n\u00e5r du st\u00f8der p\u00e5 det.<\/p>\n\n\n\n

      Forskelle mellem blyholdige og blyfri PCB'er<\/h2>\n\n\n\n

      Loddeevne<\/h3>\n\n\n\n

      Smeltepunktet for den blyfri proces er 218 grader, mens smeltepunktet for blyholdig varmluftslodning er 183 grader. Loddeevnen for blyfri loddemetal er h\u00f8jere end for blyholdigt loddemetal. Blyholdige processer har relativt d\u00e5rlig fasthed, og lodning er tilb\u00f8jelig til kolde loddeforbindelser. Men fordi temperaturen p\u00e5 blyholdige processer er relativt lav, er der mindre termisk skade p\u00e5 elektroniske produkter, og PCB-overfladen er lysere.<\/p>\n\n\n\n

      Forskelle i omkostninger<\/h3>\n\n\n\n

      I blyfri processer \u00f8ger de tinst\u00e6nger, der bruges til b\u00f8lgelodning, og de tintr\u00e5de, der bruges til manuel lodning, omkostningerne med ca. 3 gange. Omkostningerne til loddepasta, der bruges til reflow-lodning, stiger med ca. 2 gange.<\/p>\n\n\n\n

      Sikkerhed<\/h3>\n\n\n\n

      Bly er et giftigt stof. Langvarig brug skader menneskers sundhed og milj\u00f8et.<\/p>\n\n\n\n

      Selv om blyholdige processer har fordele som lavere priser og lysere overflader, er pladsen til blyholdige processer blevet mindre i de senere \u00e5r under pres fra milj\u00f8beskyttelsespolitikker. Hoved\u00e5rsagen er, at spildevandet udledes fra blyholdige PCB-processer, og n\u00e5r blyholdige PCB-produkter kasseres, uanset om de bortskaffes ved nedgravning eller forbr\u00e6nding, vil bly i sidste ende vende tilbage til milj\u00f8et gennem forskellige medier, hvilket for\u00e5rsager alvorlig blyforurening og stor skade p\u00e5 milj\u00f8et og menneskets overlevelse.<\/p>\n\n\n\n

      S\u00e5dan forebygger PCBASAIL risiko for bly<\/h2>\n\n\n\n

      Blyfri loddetr\u00e5d er naturligvis mere sikker end blyholdig loddetr\u00e5d. Men selv med blyfri loddetr\u00e5d skal man v\u00e6re opm\u00e6rksom p\u00e5 sikkerhedsbeskyttelse under brug. Desuden kommer fluxen i loddetr\u00e5den i kontakt med loddekolben ved h\u00f8j temperatur under lodning, fordamper og danner dampe. Disse dampe indeholder kolofonium og kemiske r\u00e5stoffer. Langvarig ind\u00e5nding kan for\u00e5rsage skadelige virkninger p\u00e5 menneskekroppen. Derfor er blydampe den st\u00f8rste fare, man skal beskytte sig imod under lodning. Selv n\u00e5r man bruger blyfrit loddetin, kan det indeholde spor af bly. Selvom blyfrit loddetin har mindre indvirkning end blyholdigt loddetin, skal vi beskytte os mod de mindste risici. Det er vigtigt at bruge loddetr\u00e5d, der opfylder standarderne, og tr\u00e6ffe passende beskyttelsesforanstaltninger for at sikre sundheden.<\/p>\n\n\n\n

      Samtidig skal vi ogs\u00e5 v\u00e6re klar over, at selv om blyfri loddetr\u00e5d har mindre indvirkning p\u00e5 milj\u00f8et og menneskekroppen end blyholdig loddetr\u00e5d, indeholder den stadig en vis m\u00e6ngde bly og er ikke helt uskadelig. N\u00e5r man bruger et loddejern til lodning, er det derfor afg\u00f8rende at v\u00e6lge tintr\u00e5d, der opfylder RoHS-standarderne, og tr\u00e6ffe effektive forebyggende foranstaltninger for at sikre sikkerheden i driftsprocessen.<\/p>\n\n\n\n

      Vigtige sikkerhedsforanstaltninger<\/h3>\n\n\n\n
        \n
      1. Brug handsker, masker eller gasmasker under lodning for at reducere ind\u00e5nding af blydampe.<\/li>\n\n\n\n
      2. S\u00f8rg for god ventilation p\u00e5 arbejdspladsen for at s\u00e6nke de luftb\u00e5rne blykoncentrationer.<\/li>\n\n\n\n
      3. Vask h\u00e6nder og ansigt grundigt efter arbejdet for at fjerne eventuelle blyrester p\u00e5 huden.<\/li>\n\n\n\n
      4. Planl\u00e6g rimelige arbejdspauser (f.eks. 15 minutter efter 1 times arbejde) for at mindske den fysiske belastning.<\/li>\n\n\n\n
      5. Indtag sunde vaner: reducer rygning og drik masser af vand for at hj\u00e6lpe med at skylle giftstoffer ud af kroppen.<\/li>\n<\/ol>\n\n\n\n

        Tilrettel\u00e6g arbejdstiden p\u00e5 en fornuftig m\u00e5de. Undg\u00e5 at arbejde uafbrudt i lange perioder. Hvis man f.eks. hviler sig i 15 minutter efter at have arbejdet i 1 time, hj\u00e6lper det med at reducere den fysiske belastning. Derudover hj\u00e6lper det at udvikle andre gode levevaner ogs\u00e5 med at forhindre farerne ved blydampe. For eksempel ved at reducere rygning og drikke mere vand for at fremme udskillelsen af giftstoffer fra kroppen. Gode levevaner, som f.eks. at holde op med at ryge og drikke mere vand, kan v\u00e6re med til at reducere sundhedsrisikoen ved blydampe.<\/p>\n\n\n\n

        Vigtige fakta<\/h3>\n\n\n\n
