Jikọtara ojii na aka ha

N'oge idozi, mgbawa, motherboard, na kọmputa bụ mkpa na-eji a soldering ígwè. Ma, ọ bụghị mgbe niile-adaba adaba iji, n'ihi na ọ na ngwa ngwa overheats, ọ dịghị ekwe omume na-agbanwe okpomọkụ. Ma mgbe ahụ dị gị mkpa a mobile elu rework ojii. Ogwe aka ya gburugburu ya mụtara ike omenkà.

Otu nhọrọ - na-eke a soldering ojii na-etinye na ike ọkọnọ (ihe kpomkwem, aru-ya) site soldering, na size nke iri asatọ na iri ise na ise na iri isii na ise millimeters, nke nwere ike jikọọ thereto EPSN ochie. Ka ịmepụta soldering ebe a chọrọ iji nweta iguzogide soldering okpomọkụ resistive mmetụta na onye ọzọ na nkpirikpi sting 1.6 millimeters.

Na EPSN agbakwunyere thermocouple multimeter si China. The njikwa osisi nwere ike na-size na iri anọ na atọ na iri atọ na atọ millimeters. Portable digital soldering ọdụ, na aka-ha zukọtara, na-akọ njikere iji soldering e dere na ngosipụta. Mgbe igba egbe njikwa na-agụnye ACC na-agụ ntinye na PC0, PC1 voltaji larịị. Na ikpe, ma ọ bụrụ na ọ bụ hà na ọkọnọ voltaji, otú ọ dịghị soldering, na ihe e dere «ghara ịbanye», njehie a kọrọ na-egosipụta.

Mgbe voltaji na otu onye nke ntinye bụ ihe na-erughị 4.5 volts, mgbe ahụ, ọ bụ ike ikpebi na a soldering ígwè ma ọ bụ a resistive ma ọ bụ a thermocouple. Ọzọkwa, onye ọ bụla nwere ike iji mkpọchi ka ịhazie okpomọkụ. The ngosi na-egosi na blinking ntụpọ na-agwa nke nke ngwaọrụ họrọ. Power soldering ígwè nwere ike na-achịkwa PWM mgbanwe olu VT1 isi.

Mgbe na-aga soldering ojii na aka-ha, i nwere ike ime na-enweghị mmezi transistors, n'ihi na a ugbu a nke 2 MA na-enwetara ufiop na-egbuke egbuke ìhè. Cathodes ozugbo jikọọ na njikwa ọdụ ụgbọ mmiri. Ikanam mkpa wires mkpa solder osisi na idozi n'azụ n'akụkụ site na-ekpo ọkụ gbazee nrapado.

N'ikwenye mkpọchi na ngosi mkpa ka oghere ke n'ihu panel. Ọgụgụ ebi ndụ na mirror image e biri ebi na uzo film, a na-acha ọcha tapawa-kwadoro nrapado teepu si toner ụkpụrụ bee gburugburu perimeta na mgbe glued ụlọ. N'ihi na mma nke mkpọchi dị mma na-arapara panel site na-ekpo ọkụ gbazee nrapado.

N'ihi na nwụnye ọrụ, ịkwụ ụgwọ ọzọ, dị ka motherboard ma ọ bụ PC laptọọpụ, adabara infrared soldering ọdụ, na ha onwe ha aka ime ka ọ na, kwa, bụ nnọọ ezigbo. N'ihi soldering n'elu-n'ịnyịnya biri ebi circuit iba na ya mmiri (e.g., BGA) dabara ma na-ekpo ọkụ ikuku ma ọ bụ infrared radieshon.

The ngwaọrụ mejupụtara a akara unit, emi odude ke a iche iche ụlọ. Ọ nwere ihe abụọ heaters na fixtures maka mbadamba. The ọnọdụ nke elu ga-agbanwe dabere na a ofu ego. Bottom okpomọkụ na-enye okpomọkụ mmewere maka electric ike na kilowatts nke abụọ na a dayameta nke abụọ na narị abụọ na iri abụọ na millimeters. Upper okpomọkụ - anọ tubular halogen oriọna. Onye ọ bụla n'ime ha - 150 watts. N'ihi ya, e jikọtara ọdụ, na aka-ha kpọkọtara, na-aghọ a okokụre anya.

A tripod nwere ike si na ibe nke matriks na ngwa nbipute. The ike nke details - nwekwara biiri si ochie kọmputa akụrụngwa. Egosi na-eje ozi na-akara mmiri mmiri crystal modul na a njikwa. Kama usu nkesa bụ mma iji semistors na radiators. Ọ ga-echeta na ha na-ume na ha echichi kwesịrị ịkpachara anya ka semistors. Tụkwasị na nke a dị mkpa a chọrọ iji soldering ebe ike ọkọnọ na ọ na-enye ugbu a site na abụọ ọwa, a keyboard, ngosi, ome uzu na Detector efu.

Ọ bụrụ na ị kere soldering ojii na aka-ha, na ọ dị mkpa ịmara ụfọdụ nke iwu na-arụ ọrụ na ya na nchekwa. Dị ka ihe atụ, anyị nwere ike ekwe halogen oriọna na ntụpọ na griiz. Ya mere, ha ga-enyocha kpochara na acetone ma ọ bụ mmanụ ụgbọala, na tupu ị malite na-eyi na-echebe ugogbe anya maka anwụ.
