The UCSP represents a unique packaging form factor
that may not perform equally to a packaged product
through traditional mechanical reliability tests. CSP relia-
bility is integrally linked to the user’s assembly methods,
circuit board material, and usage environment. The user
should closely review these areas when considering use
of a CSP package. Performance through Operating Life
Test and Moisture Resistance remains uncompromised
as it is primarily determined by the wafer-fabrication
process.
Mechanical stress performance is a greater considera-
tion for a CSP package. CSPs are attached through
direct solder contact to the user’s PC board, foregoing
the inherent stress relief of a packaged product lead
frame. Solder joint contact integrity must be considered.
Table 2 shows the testing done to characterize the CSP
reliability performance. In conclusion, the UCSP is capa-
ble of performing reliably through environmental stresses
as indicated by the results in the table. Additional usage
data and recommendations are detailed in the UCSP
application note, which can be found on Maxim’s web-
site at www.maxim-ic.com.
