Kuvura umuringa wuzuye umuringa: Inzira yibanze hamwe nicyizere cyingenzi cyo guhinga no kumara ubushyuhe

Kuzunguruka umuringaNibikoresho byibanze mumirongo ya elegitoroniki, nubuso bwayo nisuku byimbere byerekana neza kwizerwa muburyo bwa downchtream nko gutwika no guhinga. Iyi ngingo isesengura uburyo bwo kwivuza budasobanura imikorere yumuringa wuzuye umuringa wuzuyemo umusaruro no mubikorwa. Gukoresha amakuru nyayo, byerekana guhuza ibintu byinshi-gutunganya ubushyuhe. Civen Methord yateguye inzira yimbitse kuringaniza inyura ivanganga inganda, itanga ibisubizo byibasiye umuringa byihuse kubisubizo byo hejuru bya elegitoroniki.

1. Ikirangantego cyimikorere idahwitse: Gukuraho Ibintu Byoroshye hamwe na Grease yimbere

1.1 Ibibazo bisigaye bya peteroli muburyo buzunguruka

Mugihe cyo gukora umuringa wuzuye umuringa, umuringa urumongi rukora imirongo myinshi yo kuzunguruka kugirango ikore ibintu byiza. Kugabanya ubushyuhe bworoshye hamwe no kuzunguruka kwambara, amavuta (nk'ibinyabuzima byamavuta na synthetic esters) bikoreshwa hagati yumuzingo naUmuringahejuru. Ariko, iyi nzira iganisha ku kugumana amavuta binyuze munzira ebyiri zibanze:

• Ubudozi bwo hejuru: Munsi yigitutu cyuzuyemo, filime ya manule-ya Micron (0.1-0μm ndende) yubahiriza umuringa hejuru.
• Kwinjira imbere: Mugihe cyo guhinduranya, lattice yumuringa itezimbere indero za microscopique (nko kuganduka no ku mutima), yemerera iminyururu ya hydrocarbone (C12-C18) kwinjira mu mpimbano ukoresheje capillary hand capillary, kugera kuri did chedillary, kugera kuri 1-3μm.

1.2 Imipaka yuburyo gakondo

Uburyo busanzwe bwo kuzamura (urugero, gukaraba alkana, kunywa inzoga) gukuraho firime zamavuta gusa, kugera ku gipimo cyo gukuraho hafi70-85%, ariko ntakintu nakimbo kirwanya amavuta yinjiye mu gihugu. Ubushakashatsi bwamakuru bwerekana ko nta naga, amavuta yo mu gihugu yongeye kugaragara hejuruIminota 30 kuri 150 ° C., hamwe nigipimo cyo kongera kubitsa0.8-1.2g / m², gutera "kwanduza kabiri."

1.3 Iterambere ryikoranabuhanga muri Devereasing

Civen icyuma gikoresha a"Gukuramo imiti + Ultrasonic Igikorwa cya Ultrasonic"inzira rusange:

1. Gukuramo imiti: Umukozi wa Chella Inted (PH5-10.5) kubora imirongo miremire ya molekile, ikora ibintu byo gufunga amazi.
2. Imfashanyo ya Ultrasonic: 40Khz High-FlancyAms itanga ingaruka zo gutaka, kumena imbaraga zidasanzwe hagati ya mavuta yimbere hamwe na lattice yumuringa, kuzamura amavuta yo gusenyuka.
3. Vacuum: Umwurwazi wihuse kuri -0.08mpa igitutu kibi kirinze okiside.

Iyi nzira igabanya ibisigisigi byo gusiga≤5mg / m²(Guhura Ibipimo bya IPC-4562 bya ≤15MG / M²), Kugera> 99% Gukuraho imikorerekuri byuma byimbere.

2. Ingaruka itaziguye yo kwivuza kuri Station Lamination

2.1 Gutezimbere mu buryo bwo kuzamura porogaramu

Ibikoresho byo gutwika (nka Pi Impinduka nabafotozi) bigomba gushinga molecular-urwegoUmuringa. Amavuta asigaye aganisha ku bibazo bikurikira:

• Kugabanya ingufu zihuza: Hydrophobicity ya grease yongera inguni yo guhuza ibisubizo biva15 ° kugeza 45 °Kubangamira.
• Yabujije imiti: Amavuta yo gusiga amavuta ahagarara hydroxyl (-Oh) ku buso bw'umuringa, gukumira reaction hamwe n'amatsinda akomeye.

Kugereranya imikorere na Defreeried na Copper file isanzwe:

2.2 Kongera kwizerwa mu matara

Mugihe cyo kurenganura cyane (180-220 ° C), amavuta asigaye mumavuta yumuringa asanzwe atera kunanirwa kwinshi:

• Imiterere: Amavuta yanduye akora10-50μm bubbles(Ubucucike> 50 / cm²).
• Gutanga interlayer: Amavuta agabanya imbaraga za Van Kubara Waals hagati ya Epoxy Resin numuringa30-40%.
• Gutakaza: Amavuta yubuntu atuma ndolefore ihoraho (DK itandukanye> 0.2).

NyumaAmasaha 1000 ya 85 ° C / 85% rh gusa, Char cyumaUmuringaByera:

• Bubble ubucucike: <5 / cm² (impuzandengo yinganda> 30 / cm²).
• Imbaraga za Peel: Igumana1.6n / cm(agaciro kambere1.8n / cm, igipimo cyo gutesha agaciro 11% gusa).
• Umutekano: DK Gutandukana ≤0.05, inama5g milimeter-umuraba ibisabwa.

3. Inganda Imiterere hamwe na cyuma cya civen cyuma

3.1 INGORANE ZA Inganda: Gutwara-Gukuramo Ibiciro byoroshya

Hejuru90% by'umuringa wuzuye umuringaKoroshya gutunganya kugirango ugabanye ibiciro, ukurikira akazi k'ibanze:

Kuzunguruka → Gukaraba (Na₂co₃ Igisubizo) → Kuma → Wind

Ubu buryo bukuraho amavuta yo gusa, hamwe no gukaraba hejuru yuburere buhoraho15%(Inzira ya civen ibyuma ikomeza imbere3%).

3.2 Sinen Metal 'zeru-dekece "sisitemu yo kugenzura ubuziranenge

• Gukurikirana kumurongo: X-ray fluorescence (xRF) gusesengura igihe nyacyo cyo kumenya ibintu bisanzwe (s, cl, nibindi).
• Ibizamini bishaje bishaje: Kwigana bikabije200 ° C / 24HIbisabwa kugirango ukemure amavuta yongere kugaragara.
• Inzira Yuzuye: Buri muzingo urimo QR code yo guhuza32 Urufunguzo rwo gutunganya ibipimo(urugero, ubushyuhe budasanzwe, imbaraga za ultrasonic).

4. Umwanzuro: Kuvura-kuvumbura - Urufatiro rwibikoresho byo hejuru bya elegitoroniki

Kuvura cyane kuri umuringa wuzuye umuringa ntabwo ari ugutera imbere gusa ahubwo ni uguhuza iterambere rimwe na rimwe. Ikoranabuhanga rya CIVEN RILD RIMENKO RY'INGENZI ZIKORESHWA BYIZA KUBIKORWA BY'INTAMYI, GutangaIbyiringirokuriImikorere yo hejuru (HDI), Umuyoboro wa Flemotive, n'ibindi bice bihamye.

Muri5g na aiot ibihe, gusa ibigo birangaIkoranabuhanga ryimbereIrashobora gutwara udushya mu ntwari mu nganda za elegitoroniki.
