Ngokuvamile, ukukhiqizwa kwe-PCB kubizwa nge-Panelization ukukhulisa ukusebenza kahle kolayini wokukhiqiza we-SMT. Yimiphi imininingwane okufanele inakwe ku- Umhlangano we-PCB? Ake sikubheke.

1. Uhlaka lwe-PCB board (clamping edge) kufanele lwamukele ukwakheka kwe-loop evaliwe ukuqinisekisa ukuthi ibhodi le-PCB ngeke likhubazeke ngemuva kokuthi lilungiswe kulayini;

2, PCB ibhodi ukuma eduze ngangokunokwenzeka isikwele, Kunconywa 2 × 2, 3 × 3 …… I-Jigsaw, kepha hhayi ebhodini le-Yin ne-Yang;

3, PCB ibhodi ububanzi ≤260mm (Siemens umugqa) noma ≤300mm (FUJI umugqa); Uma ukuhanjiswa okuzenzakalelayo kuyadingeka, ububanzi x ubude bebhodi le-PCB ≤125mm × 180mm;

4, ibhodi ngalinye elincane ebhodini le-PCB kufanele libe nezimbobo okungenani ezintathu zokubeka, ukuvula okungu-3≤ ≤6 mm, imbobo yokubeka onqenqemeni ngaphakathi kwe-1mm ayivunyelwe ukwenza ucingo noma ukugoqa;

5, ibanga lesikhungo phakathi kokulawulwa kwepuleti elincane phakathi kuka-75mm ~ 145mm;

6, lapho kusethwa iphoyinti lokusetha inkomba, imvamisa endaweni yokubeka ezungeze indawo evulekile yokushisela engu-1.5mm enkulu kunaleyo;

7. Akufanele kube khona idivaysi enkulu noma idivayisi enwetshiwe eduzane nendawo yokuxhuma phakathi kohlaka lwangaphandle nocezu lwangaphakathi oluncane, futhi onqenqemeni lwezinto nebhodi le-PCB kufanele kube nesikhala esikhulu kuno-0.5mm ukuqinisekisa ukusebenza okujwayelekile kwe ithuluzi lokusika;

8. Kuvulwa izimbobo ezine zokubeka emakhoneni amane wohlaka lwangaphandle lwebhodi, ngembobo ka-4mm ± 0.01mm; Amandla omgodi kufanele abe ngokulingene ukuze kuqinisekiswe ukuthi ngeke aqhekeke ngenkathi kusetshenziswa amapuleti aphezulu nangaphansi; Imbobo kanye nokunemba kwesikhundla kube phezulu, okushelelayo odongeni lomgodi ngaphandle kwe-burr;

9. Ngokuyinhloko, i-QFP enesikhala esingaphansi kuka-0.65mm izobekwa endaweni ehlukanisiwe yophawu oluyinkomba lokuma kwebhodi yonke ye-PCB nokubekwa kahle kwedivayisi; Izimpawu zokubekwa kwezimpawu zamabhodi angaphansi kwe-PCB kufanele zisetshenziswe ngababili futhi zihlelwe ngokuhlukaniswa kwezinto zokubeka;

10, izingxenye ezinkulu kufanele zibe namakholomu wokubeka noma izimbobo zokubeka, njenge-interface ye-I / O, imakrofoni, isikhombimsebenzisi sebhethri, iswishi encane, isikhombimsebenzisi sekhanda, imoto, njll.
