Kumvetsetsa DIP
DIP ndi pulogalamu yowonjezera. Chips mmatumba motere ndi mizere iwiri ya zikhomo, amene akhoza mwachindunji welded kuti chip sockets ndi dongosolo DIP kapena welded kuti kuwotcherera maudindo ndi chiwerengero chomwecho mabowo. Ndi yabwino kwambiri kuzindikira PCB bolodi perforation kuwotcherera, ndipo ali ngakhale wabwino ndi mavabodi, koma chifukwa cha ma CD malo ake ndi makulidwe ndi lalikulu, ndi pini mu ndondomeko kulowetsa ndi kuchotsa n'zosavuta kuonongeka, osauka kudalirika.
DIP ndi phukusi lodziwika bwino la plug-in, mawonekedwe ogwiritsira ntchito amaphatikizapo logic yokhazikika IC, kukumbukira LSI, maulendo a microcomputer, etc. Phukusi laling'ono laling'ono (SOP), lochokera ku SOJ (J-mtundu wa pini yaing'ono phukusi), TSOP (yoonda yaying'ono phukusi la mbiri), VSOP (phukusi lambiri laling'ono kwambiri), SSOP (yochepetsedwa SOP), TSSOP (yoonda yochepetsedwa SOP) ndi SOT (transistor yaying'ono), SOIC (gawo laling'ono lophatikizika), ndi zina zambiri.
Kuwonongeka kwa kapangidwe ka chipangizo cha DIP
Bowo la phukusi la PCB ndi lalikulu kuposa chipangizocho
Mabowo a pulagi a PCB ndi mabowo a pini amakokedwa motsatira zomwe zafotokozedwa. Chifukwa cha kufunikira kwa plating yamkuwa m'mabowo pakupanga mbale, kulolerana kwanthawi zonse ndikophatikiza kapena kuchotsera 0.075mm. Ngati dzenje PCB ma CD ndi lalikulu kwambiri kuposa pini ya chipangizo thupi, zingachititse kuti tithe kumasula chipangizo, malata osakwanira, kuwotcherera mpweya ndi mavuto ena khalidwe.
Onani chithunzi pansipa, ntchito WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) pini chipangizo ndi 1.3mm, PCB ma CD dzenje ndi 1.6mm, kabowo ndi lalikulu kwambiri kutsogolera pa mafunde kuwotcherera danga nthawi kuwotcherera.
Zophatikizidwa ndi chiwerengerocho, gulani zigawo za WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) malinga ndi zofunikira za mapangidwe, pini 1.3mm ndiyolondola.
Bowo la phukusi la PCB ndilocheperako kuposa chipangizocho
Pulagi-mu, koma dzenje palibe mkuwa, ngati ali limodzi ndi mapanelo awiri angagwiritse ntchito njira imeneyi, limodzi ndi iwiri mapanelo ndi kunja magetsi conduction, solder akhoza conductive; Pulagi-mu dzenje la multilayer bolodi ndi laling'ono, ndipo PCB bolodi akhoza remated kokha ngati wosanjikiza wamkati ali conduction magetsi, chifukwa mkati wosanjikiza conduction sangathe kukonzedwa ndi reaming.
Monga momwe zasonyezedwera pachithunzichi, zigawo za A2541Hwv-3P_A2541HWV-3P (CJT) zimagulidwa malinga ndi zofunikira za mapangidwe. Piniyo ndi 1.0mm, ndipo dzenje losindikizira la PCB ndi 0.7mm, zomwe zimapangitsa kulephera kuyika.
Zigawo za A2541Hwv-3P_A2541HWV-3P (CJT) zimagulidwa malinga ndi zofunikira za mapangidwe. Pini 1.0mm ndiyolondola.
Kutalikirana kwa mapini a phukusi kumasiyana ndi katalikirana ka zida
Chisindikizo cha PCB chosindikizira cha chipangizo cha DIP sichingokhala ndi kabowo kofanana ndi pini, komanso chimafunikanso mtunda womwewo pakati pa mabowo a pini. Ngati kusiyana pakati pa mabowo a pini ndi chipangizocho sikukugwirizana, chipangizocho sichingalowetsedwe, kupatulapo magawo omwe amatha kusintha mapazi.
Monga momwe chithunzi chili pansipa, pini dzenje mtunda wa PCB ma CD ndi 7.6mm, ndi pini dzenje mtunda wa zigawo anagula ndi 5.0mm. Kusiyana kwa 2.6mm kumapangitsa kuti chipangizocho chikhale chosagwiritsidwa ntchito.
Mabowo a PCB ali pafupi kwambiri
Pakujambula kwa PCB, kujambula ndi kuyika, ndikofunikira kulabadira mtunda pakati pa mabowo a pini. Ngakhale mbale yopanda kanthu ikhoza kupangidwa, mtunda wapakati pa mabowo a pini ndi wochepa, ndizosavuta kuchititsa kuti tini tizikhala ndifupipafupi panthawi ya msonkhano ndi soldering yoweyula.
Monga momwe tawonetsera m'chithunzichi, kufupika kwafupipafupi kungayambitsidwe ndi mtunda wawung'ono wa pini. Pali zifukwa zambiri zafupipafupi muzitsulo za soldering. Ngati kusonkhana kungalepheretsedwe pasadakhale kumapeto kwa mapangidwe, chiwerengero cha mavuto chikhoza kuchepetsedwa.
DIP chipangizo pini vuto vuto
Kufotokozera zavuto
Pambuyo kuwotcherera yoweyula wa mankhwala DIP, anapeza kuti panali kusowa kwambiri malata pa solder mbale ya phazi lokhazikika la zitsulo maukonde, amene anali kuwotcherera mpweya.
Zotsatira zavuto
Chotsatira chake, kukhazikika kwa socket network ndi PCB board kumakhala koipitsitsa, ndipo mphamvu ya phazi la pini idzagwiritsidwa ntchito pogwiritsira ntchito mankhwala, zomwe pamapeto pake zidzatsogolera kugwirizana kwa phazi la pini, zomwe zimakhudza mankhwala. magwiridwe antchito ndikupangitsa chiopsezo cholephera kugwiritsa ntchito ogwiritsa ntchito.
Kukulitsa vuto
Kukhazikika kwa socket ya network ndi koyipa, kulumikizidwa kwa pini yazizindikiro ndi koyipa, pali zovuta zamtundu, kotero zimatha kubweretsa zoopsa zachitetezo kwa wogwiritsa ntchito, kutayika komaliza sikungaganizidwe.
Kuwunika kusanthula kwa chipangizo cha DIP
Pali mavuto ambiri okhudzana ndi zikhomo za chipangizo cha DIP, ndipo mfundo zambiri zazikulu ndizosavuta kunyalanyazidwa, zomwe zimapangitsa kuti pakhale bolodi lomaliza. Ndiye momwe mungathetsere mavuto oterowo mwachangu komanso kotheratu?
Pano, ntchito yosonkhanitsa ndi kusanthula pulogalamu yathu ya CHIPSTOCK.TOP ingagwiritsidwe ntchito poyang'ana mwapadera pamapini a zipangizo za DIP. Zinthu zowunikira zimaphatikizapo kuchuluka kwa zikhomo kudzera m'mabowo, malire akulu a mapini a THT, malire ang'onoang'ono a mapini a THT ndi mawonekedwe a zikhomo za THT. Zinthu zowunikira pamapini zimaphimba zovuta zomwe zingatheke pakupanga zida za DIP.
Akamaliza mapangidwe PCB, PCBA msonkhano kusanthula ntchito angagwiritsidwe ntchito kupeza zolakwika kapangidwe pasadakhale, kuthetsa anomalies kapangidwe pamaso kupanga, ndi kupewa mavuto kamangidwe mu ndondomeko msonkhano, kuchedwa kupanga nthawi ndi zinyalala kafukufuku ndi chitukuko ndalama.
Ntchito yake yowunikira msonkhano ili ndi zinthu zazikulu 10 ndi malamulo oyendera zinthu 234, zomwe zimakhudza zovuta zonse zomwe zingachitike pagulu, monga kusanthula kwa zida, kusanthula mapini, kusanthula kwapadi, ndi zina zambiri, zomwe zimatha kuthana ndi zochitika zosiyanasiyana zopanga zomwe mainjiniya sangathe kuziyembekezera.
