Ndi chitukuko chachangu cha makampani zamagetsi, PCB mawaya akukhala mochulukira kwambiri. Ambiri PCB opanga amagwiritsa ntchito filimu youma kuti amalize kusamutsidwa kwazithunzi, ndipo kugwiritsa ntchito filimu youma kukuchulukirachulukira. Komabe, ndimakumanabe ndi mavuto ambiri pakugulitsa ntchito pambuyo pogulitsa. Makasitomala ali ndi kusamvetsetsana kochuluka akamagwiritsa ntchito filimu yowuma, yomwe ili mwachidule apa kuti afotokoze.

Momwe mungasinthire zovuta za kanema wa PCB

1. Pali mabowo mu filimu yowuma chigoba
Makasitomala ambiri amakhulupirira kuti dzenje likachitika, kutentha ndi kupanikizika kwa filimuyo ziyenera kuwonjezeredwa kuti ziwonjezere mphamvu yake yolumikizana. M’malo mwake, malingaliro awa ndi olakwika, chifukwa chosungunulira cha chosanjikiza chokanirira chidzasungunuka kwambiri pambuyo pa kutentha ndi kupanikizika kwambiri, zomwe zingayambitse kuuma. Firimuyi imakhala yovuta komanso yochepa, ndipo mabowo amasweka mosavuta panthawi ya chitukuko. Tiyenera kukhalabe kuuma kwa filimu youma. Chifukwa chake, pambuyo powonekera mabowo, titha kusintha kuchokera pazifukwa izi:

1. Kuchepetsa kutentha ndi kupanikizika kwa filimuyi

2. Kuwongolera kuboola ndi kuboola

3. Wonjezerani mphamvu zowonetsera

4. Chepetsani kupanikizika

5. Pambuyo pomamatira filimuyo, nthawi yoyimitsa magalimoto isakhale yotalika kwambiri, kuti musapangitse kuti filimu ya mankhwala a semi-fluid pakona ifalikire ndi kuonda pansi pa kukakamizidwa.

6. Osatambasula filimu yowuma molimba kwambiri panthawi yodutsa

Chachiwiri, plating plating kumachitika pa youma filimu electroplating
Chifukwa cha kulowetsedwa ndi chakuti filimu yowuma ndi bolodi lamkuwa silimangiriridwa mwamphamvu, kotero kuti njira yothetsera plating ndi yakuya, ndipo gawo la “negative” la chophimba limakula kwambiri. The permeation wa opanga PCB ambiri amayamba ndi mfundo zotsatirazi:

1. Mphamvu zowonetsera ndizokwera kwambiri kapena zochepa

Pansi pa kuwala kwa kuwala kwa ultraviolet, photoinitiator yomwe yatenga mphamvu ya kuwala imawonongeka kukhala ma radicals aulere kuti ayambitse photopolymerization reaction kuti apange molekyulu yooneka ngati thupi yomwe imakhala yosasungunuka mu njira ya alkali yosungunuka. Pamene kuwonetseredwa sikuli kokwanira, chifukwa cha polymerization yosakwanira, filimuyo imatupa ndipo imakhala yofewa panthawi yachitukuko, zomwe zimapangitsa kuti mizere yosadziwika bwino kapena kupukuta filimuyo, zomwe zimapangitsa kuti filimuyi ikhale yosagwirizana ndi mkuwa; ngati kuwonetseredwa kuchulukirachulukira, kumayambitsa zovuta zachitukuko komanso panthawi ya electroplating. Kuwotcha ndi kukwapula kunachitika panthawi ya ndondomekoyi, kupanga plating yolowera. Choncho, ndikofunika kwambiri kulamulira mphamvu zowonetsera.

2. Kutentha kwa kanema ndikokwera kwambiri kapena kutsika

Ngati kutentha kwa filimuyo kuli kochepa kwambiri, filimu yotsutsa silingathe kuchepetsedwa mokwanira ndikuthamanga bwino, zomwe zimapangitsa kuti pakhale kusamata bwino pakati pa filimu youma ndi pamwamba pa laminate yamkuwa; ngati kutentha kuli kwakukulu kwambiri, zosungunulira ndi zina zosasunthika mu kukana Kuthamanga kwachangu kwa chinthu kumatulutsa thovu, ndipo filimu yowuma imakhala yosasunthika, yomwe imayambitsa kumenyana ndi kupukuta panthawi ya electroplating kugwedezeka kwamagetsi, zomwe zimabweretsa kulowetsa.

3. Kuthamanga kwa kanema ndikokwera kwambiri kapena kochepa

Pamene kupanikizika kwa filimu kumakhala kochepa kwambiri, kungayambitse filimu yosagwirizana kapena mipata pakati pa filimu yowuma ndi mbale yamkuwa ndikulephera kukwaniritsa zofunikira za mphamvu yogwirizanitsa; ngati kupanikizika kwa filimu kuli kwakukulu kwambiri, zigawo zosungunulira ndi zosasunthika za zosanjikiza zosanjikiza zidzasungunuka kwambiri, zomwe zimapangitsa Firimu yowuma imakhala yovuta ndipo idzakwezedwa ndi kupukuta pambuyo pa electroplating electric shock.
