Na mmepe nke miniaturization na nkenke nke electronic ngwaahịa, naPCB mgbakọ n'ichepụtana njupụta mgbakọ nke ụlọ ọrụ nhazi eletrọnịkị na-eji na-emewanyewanye elu, nkwonkwo ndị na-ere ahịa na bọọdụ sekit na-adịwanye ntakịrị, na ígwè ọrụ, eletriki na thermodynamic ha na-ebu na-ebuwanye elu.Ọ na-adị arọ karị na ihe ndị a chọrọ maka nkwụsi ike na-abawanye.Otú ọ dị, nsogbu nke PCB mgbakọ solder nkwonkwo ọdịda ga-ezute na n'ezie nhazi usoro.Ọ dị mkpa iji nyochaa ma chọpụta ihe kpatara ya iji zere ọdịda nkwonkwo solder na-eme ọzọ.
Ya mere, taa, anyị ga-ewebata gị isi ihe kpatara ọdịda nke PCB mgbakọ nhazi solder nkwonkwo.
Isi ihe kpatara ọdịda nke PCB ọgbakọ nhazi solder nkwonkwo:
1. Ogbenye akụrụngwa atụdo: plating, mmetọ, oxidation, coplanarity.
2. Ogbenye PCB mpe mpe akwa: plating, mmetọ, oxidation, warpage.
3.Solder àgwà ntụpọ: mejupụtara, adịghị ọcha substandard, oxidation.
4. Flux àgwà ntụpọ: obere flux, elu corrosion, ala SIR.
5. Mmebi njikwa ihe nhazi usoro: imewe, njikwa, akụrụngwa.
6. Ihe ndị ọzọ na-enye aka ntụpọ: adhesives, onye na-ehicha ihe.
Ụzọ nke ịbawanye nkwụsi ike nke nkwonkwo solder mgbakọ PCB:
Nnwale nkwụsi ike nke nkwonkwo solder PCB na-agụnye nnwale nkwụsi ike na nyocha.
N'otu aka ahụ, nzube ya bụ iji nyochaa na chọpụta nkwụsi ike larịị nke PCB mgbakọ integrated circuit ngwaọrụ, na inye parameters maka nkwụsi ike imewe nke dum igwe.
N'aka nke ọzọ, na usoro nkePCB mgbakọnhazi, ọ dị mkpa iji melite nkwụsi ike nke nkwonkwo solder.Nke a chọrọ nyocha nke ngwaahịa dara ada, iji chọpụta ọnọdụ ọdịda, yana nyochaa ihe kpatara ọdịda.Ebumnobi a bụ iji megharịa ma melite usoro imewe, structural parameters, welding process, and improve the fruit of PCB meeting processing.The ọdịda mode nke PCB mgbakọ solder nkwonkwo bụ ndabere maka ịkọ ya okirikiri ndụ na guzosie ike ya mgbakọ na mwepụ nlereanya.
Na okwu, Anyị kwesịrị melite nkwụsi ike nke solder nkwonkwo na melite mkpụrụ nke ngwaahịa.
