Tinyegharịa ọnọdụ okpomọkụ nke mpaghara oven yana profaịlụ okpomọkụ

Usoro nke ikuku na-ekpo ọkụ reflow soldering bụ n'ezie usoro nnyefe okpomọkụ.Tupu ịmalite “esi nri” bọọdụ ebumnuche, ọ dị mkpa ka edobe okpomọkụ mpaghara oven reflow.

Okpomọkụ mpaghara ọkụ reflow bụ ebe atọrọ ebe a ga-ekpo ọkụ ọkụ ka ọ ruo ebe atọrọ okpomọkụ a.Nke a bụ usoro njikwa aka mechiri emechi na-eji echiche njikwa PID ọgbara ọhụrụ.A ga-enyeghachi data nke okpomọkụ ikuku na-ekpo ọkụ n'akụkụ ihe ọkụkụ a dị iche iche na onye nchịkwa, nke kpebiri ịgbanwuo ma ọ bụ gbanyụọ ike ọkụ.

Enwere ọtụtụ ihe na-emetụta ikike bọọdụ ahụ iji kpoo ọkụ nke ọma.Ihe ndị bụ isi bụ:

1. Okpomọkụ PCB mbụ

N'ọtụtụ ọnọdụ, PCB mbụ okpomọkụ bụ otu ihe ahụ dị ka okpomọkụ ụlọ.Ka ọdịiche dị n'etiti PCB okpomọkụ na oven ụlọ okpomọkụ, ngwa ngwa PCB osisi ga-ekpo ọkụ.

1. Tinyegharịa okpomọkụ ụlọ oven

Okpomọkụ ụlọ ọkụ na-emegharị bụ ikuku ikuku na-ekpo ọkụ.Ọ nwere ike jikọta ya na okpomọkụ nhazi oven ozugbo;Otú ọ dị, ọ bụghị otu ihe ahụ na uru nke ntọala ntọala.

1. Nguzogide okpomọkụ nke nnyefe ọkụ

Ihe ọ bụla nwere nguzogide okpomọkụ.Ọla nwere obere nguzogide okpomọkụ karịa ihe ndị na-abụghị metal, yabụ ọnụ ọgụgụ nke PCB n'ígwé na ọkpụrụkpụ cooper ga-emetụta nnyefe okpomọkụ.

1. PCB thermal capacitance

PCB thermal capacitance na-emetụta nkwụsi ike okpomọkụ nke bọọdụ ebumnuche.Ọ bụkwa isi ihe n'inweta ezigbo soldering.Ọkpụrụkpụ PCB na ikike okpomọkụ nke akụrụngwa ga-emetụta nnyefe ọkụ.

Nkwubi okwu bụ:

Okpomọkụ nhazi oven abụghị kpọmkwem otu okpomọkụ PCB.Mgbe ịchọrọ ịkwalite profaịlụ reflow, ị ga-enyocha paramita bọọdụ dị ka ọkpụrụkpụ bọọdụ, ọkpụrụkpụ ọla kọpa, na ihe ndị mejupụtara yana ịmara ikike oven reflow gị nke ọma.
