O le a le mea e faʻalogo i ai pe a mamanuina PCBA Circuit Boards?

1. Vaega masani e tatau ona gauai atu i le tele o le faapalepale o vaega gaosi eseese, e tatau ona mamanuina vaega e le masani ai e tusa ai ma le tele moni o vaega pad graphics ma pad spacing.

2. O le mamanu o le maualuga-faʻatuatuaina matagaluega e tatau ona faʻalauteleina solder plate processing, pad lautele = 1.1 i 1.2 taimi le lautele o vaega solder pito.

3. Fuafuaga maualuga i le faletusi polokalama o vaega e faʻasaʻo ai le tele o le pad.

4. O le mamao i le va o vaega eseese, uaea, suʻega suʻega, ala-pu, pads ma fesoʻotaʻiga uaea, solder resistance, ma isi e tatau ona mamanuina e tusa ai ma faiga eseese.

5. Mafaufau i le toe faʻaaogaina.

6. Mafaufau i le vevela vevela, maualuga taimi, faʻalavelave faʻafefe eletise ma isi mataupu.

7. o le tuʻuina atu o vaega ma le faʻatonuga e tatau ona mamanuina e tusa ai ma manaʻoga o le toe faʻaleleia poʻo le galu solder process.Mo se faʻataʻitaʻiga, pe a faʻaaogaina le faʻaogaina o le soldering process, o le faʻatonuga o le faʻatonuga o vaega e mafaufau i le itu o le PCB i totonu o le umu reflow.Pe a faʻaaogaina masini faʻapipiʻi galu, e le mafai ona tuʻuina le masini PLCC, FP, fesoʻotaʻiga ma vaega tele SOIC;ina ia faʻaitiitia le aʻafiaga o le galu, faʻaleleia le lelei o le uʻamea, le faʻatulagaina o vaega eseese ma le nofoaga o manaʻoga faʻapitoa;wave solder pad design graphics, rectangular parts, SOT, SOP parts pad length e tatau ona fa'alautele e fa'atatau i le pito i fafo e lua SOP Wider pairs of solder pads to adsorb solder solder, less than 3.2mm × 1.6mm rectangular parts, can be chamfered i lua. pito o le pad 45 ° faagasologa, ma isi.

8. Lomitusi mamanu laupapa matagaluega mafaufau foi i meafaigaluega.Eseese fa'apipi'i masini fausaga fa'ainisinia, alignment, lolomi laupapa matagaluega fa'asalalau e eseese, o lea o le tulaga o le nofoaga lomi laupapa matagaluega pu, fa'ailoga fa'ailoga (Fa'ailoga) ata ma le nofoaga, lolomi laupapa matagaluega foliga foliga, fa'apea fo'i ma le pito laupapa matagaluega lolomi lata ane. e le mafai ona tuʻuina le nofoaga o vaega e iai manaʻoga eseese.Afai e faʻaaogaina le faʻaogaina o le galu, e tatau foi ona mafaufau i le faʻagasologa o le pito o le filifili faʻasalalau laupapa eletise lolomi e tatau ona tuʻu.

9. Ae ia mafaufau foi i pepa mamanu talafeagai.

10. ia fa'aitiitia tau o le gaosiga i lalo o le fa'amoemoe e fa'amautinoa le fa'atuatuaina.

11. le mamanu laupapa matagaluega lolomi tutusa, o le faaaogaina o iunite e tatau ona ogatasi.

12. Fa'apotopotoga fa'alua itu ma le fa'apotopotoga tasi-itu o lo'o mana'omia mamanu laupapa fa'asalalau lolomi e tutusa

13. Ae ia mafaufau foi i pepa mamanu talafeagai.
