Akpachara anya maka PCB Welding

1. Na-echetara onye ọ bụla ka ọ buru ụzọ lelee ọdịdị ahụ mgbe ị nwetasịrị PCB bare board iji hụ ma enwere obere sekit, nkwụsịtụ na nsogbu ndị ọzọ.Mara nke ọma na eserese atụmatụ bọọdụ mmepe, ma tulee eserese schematic na oyi akwa obibi akwụkwọ PCB ka ịzena ọdịiche dị n'etiti eserese schematic na PCB.

2. Mgbe ihe ndị a chọrọreflow ovendị njikere, na components kwesịrị nkewa.All components nwere ike kewaa n'ime ọtụtụ edemede dị ka nha ha maka ịdị mma nke ịgbado ọkụ na-esote.Ekwesịrị ibipụta ndepụta ihe zuru oke.N'ime usoro ịgbado ọkụ, ọ bụrụ na ọ nweghị ịgbado ọkụ agwụla, jiri pen were were pen were were nhọrọ ndị kwekọrọ ekwekọ mee ka ọ dị mfe ọrụ ịgbado ọkụ na-esote.

3. Tupuigwe reflow soldering, Were usoro esd, dị ka iyi mgbanaka esd, iji gbochie mmebi nke ihe ndị na-emepụta ihe.Ka emechara ngwa ịgbado ọkụ niile, hụ na isi igwe a na-ere ere dị ọcha ma dịkwa mma.A na-atụ aro ka ịhọrọ igwe nrịbama akụkụ dị larịị maka ịgbado ọkụ mbụ.Mgbe ịgbado ọkụ encapsulated components dị ka 0603 ụdị, soldering ígwè nwere ike mma ịkpọtụrụ welding pad, nke dị mma maka ịgbado ọkụ.N'ezie, maka nna ukwu, nke a abụghị nsogbu.

4. Mgbe ị na-ahọrọ components maka ịgbado ọkụ, weld ha n'usoro site na ala ruo elu na site na obere ka nnukwu.Iji zere ịgbado ọkụ erughị ala nke welded ibu components ka nta components.Ọkachamma weld agbakwunyere ibe sekit.

5. Tupu ịgbado ọkụ integrated circuit ibe, hụ na ibe na-enịm na ziri ezi ntụziaka.Maka oyi akwa ebipụta ihuenyo mgbawa, pad akụkụ anọ na-anọchi anya mmalite nke pin.N'oge ịgbado ọkụ, a ga-ebu ụzọ dozie otu ntụtụ nke mgbawa.Mgbe edozichara ọnọdụ nke ihe ndị ahụ, a ga-edozi ntụtụ diagonal nke mgbawa ka ihe ndị ahụ wee jikọọ nke ọma na ọnọdụ ahụ tupu ịgbado ọkụ.

6. Ọ dịghị mma ma ọ bụ na-adịghị mma electrode na seramiiki mgbawa capacitors na regulator diodes na voltaji regulator sekit, ma ọ dị mkpa ịmata ọdịiche dị mma na adịghị mma electrode maka leds, tantalum capacitors na electrolytic capacitors.Maka akụrụngwa capacitors na diode, njedebe akara ga-adịkarị njọ.Na ngwugwu nke SMT LED, enwere ụzọ dị mma - na-adịghị mma n'akụkụ ntụziaka nke oriọna.Maka ihe ndị nwere mkpuchi mkpuchi silk ihuenyo njirimara nke eserese sekit diode, a ga-etinye oke diode na-adịghị mma na njedebe nke ahịrị kwụ ọtọ.

7. maka oscillator kristal, oscillator kristal na-agafe agafe n'ozuzu naanị ntụtụ abụọ, na enweghị isi ihe dị mma na nke na-adịghị mma.Oscillator kristal na-arụ ọrụ n'ozuzu nwere ntụtụ anọ.Lezienụ anya na nkọwa nke ntụtụ ọ bụla iji zere njehie ịgbado ọkụ.

8. N'ihi na ịgbado ọkụ nke plug-in components, dị ka ike modul metụtara components, pin nke ngwaọrụ nwere ike gbanwee tupu ịgbado ọkụ.Mgbe etinyechara ma dozie ihe ndị ahụ, a na-agbaze ihe na-ere ya site na igwe na-ere ahịa n'azụ ma tinye ya n'ihu site na pad solder.Etinyela oke solder, mana nke mbụ ihe mejupụtara ya kwesịrị ịdị nhịahụ.

9. PCB imewe nsogbu achọtara n'oge ịgbado ọkụ kwesịrị ka e dekọrọ na oge, dị ka echichi nnyonye anya, na-ezighị ezi pad size imewe, akụrụngwa nkwakọ njehie, wdg, n'ihi na ụdi mma.

10. mgbe ịgbado ọkụ, jiri iko na-ebuwanye ibu iji lelee nkwonkwo solder wee lelee ma enwere ntụpọ weld ma ọ bụ obere sekit.

11. mgbe emechara ọrụ ịgbado ọkụ nke sekit, mmanya na ihe ndị ọzọ na-ehicha ihe kwesịrị iji mee ka ọ dị ọcha n'elu ihe nkedo ahụ, iji gbochie eriri ụgbọ mmiri na-ejikọta ya na mgbawa ígwè nke dị mkpirikpi, ma ọ pụkwara ime ka bọọdụ sekit. ọzọ dị ọcha na mara mma.
