Procesni tok aluminijaste podlage

1. Odpiranje

Postopek izdelave aluminijaste podlage

1. Postopek rezanja materiala - rezanje

2. Namen odpiranja

Izrežite velike-dohodne materiale na velikost, ki je potrebna za proizvodnjo

3. Varnostni ukrepi za materiale za odpiranje

① Check the size of the first piece after cutting

② Pay attention to the scratches on the aluminum surface and the scratches on the copper surface

③ Pay attention to the layering and draping of the edge of the board

2. Vrtanje

1. Postopek vrtanja

Vstavljanje moznikov - Vrtanje - Kontrolna plošča

2. Namen vrtanja

Postavitev in vrtanje plošče za pomoč pri nadaljnjem proizvodnem procesu in montaži stranke

3. Varnostni ukrepi pri vrtanju

① Check the number of drilled holes and the size of the holes

② Avoid scratches on the sheet

③ Check the drape of the aluminum surface and the deviation of the hole position

④ Check and replace the drill bit in time

⑤ Drilling is divided into two stages, one drilling: after cutting the material, the drilling is a peripheral tool hole

Drugi vrtalnik: luknja za orodje v enoti po spajkalni maski

3. Slikanje suhega/mokrega filma

1. Postopek slikanja s suhim/mokrim filmom

Brusilna plošča - film - izpostavljenost - razvoj

2. Namen slikanja s suhim/mokrim filmom

Deli, potrebni za izdelavo vezja, so upodobljeni na listu

3. Previdnostni ukrepi pri slikanju s suhim/mokrim filmom

① Check whether there is an open circuit in the circuit after developing

② Whether there is any deviation in the development alignment to prevent the occurrence of dry film breakage

③ Pay attention to the defective circuit caused by scratches on the board surface

④ There should be no air residue during exposure to prevent poor exposure

⑤ After exposure, keep it still for more than 15 minutes before developing

4. Kislinsko/alkalno jedkanje

1. Kislinsko/alkalno jedkanje

Jedkanje - odstranjevanje - sušenje - inšpekcijska plošča

2. Namen kislinskega/alkalnega jedkanja

Po slikanju suhega/mokrega filma ohranite zahtevani del vezja, odstranite odvečni del izven vezja in bodite pozorni na korozijo aluminijaste podlage z raztopino za jedkanje med kislinskim jedkanjem;

3. Previdnostni ukrepi za kislinsko/alkalno jedkanje

① Note that the etching is not clean and the etching is excessive

② Pay attention to line width and line thickness

③ The copper surface is not allowed to be oxidized or scratched

④ The dry film should be removed cleanly

Petica, maska ​​za spajkanje na svileni sitotiki, znaki

1. Silk screen spajkalna maska, proces znakov

Silkscreen - Pred-pečenje - Izpostavljenost - Razvoj - Liki

2. Namen spajkalne maske za sito sito in znakov

① Anti-soldering: protect the circuit that does not need to be soldered and prevent the tin from entering and causing a short circuit

② Characters: play the role of marking

3. Zadeve, ki zahtevajo pozornost za spajkalno masko za sito sito in znake

① To check whether there is garbage or foreign matter on the board

COB aluminijasta podlaga

COB aluminijasta podlaga

② Check the cleanliness of the stencil ③ Pre-bake for more than 30 minutes after screen printing to avoid bubbles in the lines

④ Pay attention to the thickness and uniformity of the silk screen

⑤ After pre-baking, the board should be completely cooled to avoid sticking to the film or destroying the gloss of the ink surface.

⑥ Place the ink face down during development

6. V-CUT, gong deska

1. V-CUT, postopek gong deske

V-CUT——Gong board——Tear off protective film——Remove Pifeng

2, V-CUT, namen gong deske

① V-CUT: Connect a single PCS line to the whole PNL plate cutting and leave a small part for easy packaging and removal.

② gong board: remove the excess part of the circuit board

3. Previdnostni ukrepi za V-CUT in gong desko

① During the V-CUT process, pay attention to the size of V, incomplete edges and burrs

② Pay attention to burrs when the gong board is used, and the gong knife is skewed. Check and replace the gong knife in time.

③ Finally, avoid scratches on the board when removing the front.

Sedem, test, OSP

1. Test, OSP proces

Preskus linije - Preskus vzdržljive napetosti - OSP

2. Testiranje, namen OSP

① Line test: check whether the completed line is working normally

② Withstand voltage test: check whether the completed line can withstand the specified voltage environment

③ OSP: Make the circuit better for soldering

3, testiranje, previdnostni ukrepi OSP

① How to distinguish between qualified and unqualified products after testing

② Placement after finishing OSP

③ Avoid line damage

Osem, FQC, FQA, pakiranje, pošiljanje

1. Proces

FQC - FQA - Pakiranje - Pošiljka

2. Namen

① FQC conducts full inspection and confirmation of the product

② FQA random inspection and verification

③ Pack and ship to customers as required

3. Bodite pozorni

① FQC pays attention to the confirmation of appearance during the visual inspection process and makes a reasonable distinction

② FQA really conducts random inspections to verify the inspection standards of FQC

③ To confirm the number of packages, avoid mixed boards, wrong boards and package damage 3
