Ihe ndị na-emetụta àgwà reflow soldering

Ihe na-emetụta ogo reflow soldering bụ ndị a

1. Mmetụta ihe nke solder mado
Ogo nke reflow soldering na-emetụta ọtụtụ ihe.Ihe kacha mkpa bụ okpomọkụ usoro nke reflow ọkụ na mejupụtara parameters nke solder mado.Ugbu a igwe ọkụ ịgbado ọkụ na-arụ ọrụ dị elu enweela ike ijikwa ma mezie usoro okpomọkụ nke ọma.N'ụzọ dị iche, na omume nke elu njupụta na miniaturization, solder mado obibi aghọwo isi ihe na reflow soldering àgwà.
The urughuru udi nke solder mado alloy ntụ ntụ metụtara ịgbado ọkụ àgwà nke warara spacing ngwaọrụ, na viscosity na mejupụtara nke solder mado ga-ahọrọ nke ọma.Tụkwasị na nke ahụ, a na-echekwa pasta nchara na nchekwa oyi, na mkpuchi nwere ike imeghe naanị mgbe eweghachiri okpomọkụ n'ime ụlọ.Ekwesịrị ịkwụ ụgwọ nlebara anya pụrụ iche iji zere ịgwakọta tapawa ihe na-ere ihe na vapo mmiri n'ihi ọdịiche okpomọkụ.Ọ bụrụ na ọ dị mkpa, gwakọta tapawa solder na igwekota.

2. Mmetụta nke akụrụngwa ịgbado ọkụ
Mgbe ụfọdụ, ịma jijiji nke eriri eriri nke akụrụngwa ịgbado ọkụ reflow bụkwa otu n'ime ihe na-emetụta ogo ịgbado ọkụ.

3. Mmetụta nke reflow ịgbado ọkụ usoro
Mgbe i wepụrụ àgwà na-adịghị mma nke usoro mbipụta akwụkwọ nke solder na usoro SMT, usoro reflow n'onwe ya ga-edugakwa n'ụdị àgwà ndị a:
① Na ịgbado ọkụ oyi, okpomọkụ reflow dị ala ma ọ bụ oge mpaghara reflow ezughị.
② Ọnọdụ okpomọkụ dị na mpaghara preheating nke tin bead na-ebili ngwa ngwa (n'ozuzu, mkpọda okpomọkụ na-erughị ogo 3 kwa nkeji).
③ Ọ bụrụ na mmiri na-emetụta bọọdụ sekit ma ọ bụ ihe mejupụtara ya, ọ dị mfe ime ka mgbawa tin ma mepụta tin na-aga n'ihu.
④ N'ozuzu, okpomọkụ dị na mpaghara jụrụ oyi na-ada ngwa ngwa (n'ozuzu, ọnọdụ okpomọkụ na-ada ada nke ịgbado ọkụ na-erughị 4 degrees kwa nkeji).
