ALPHA OM-372 offers best-in-class electrochemical reliability
Miniaturization is creating new challenges for ensuring reliability of solder pastes on more complex, densely populated PCB designs. To address these challenges, Alpha developed a proprietary test to assess the ability of a solder paste to withstand electromigration on 0.100mm spaced, hermetically sealed comb patterns representative of the conditions typical of low standoff package designs. ALPHA OM-372 is designed to maintain SIR values >10^8 with no evidence of electromigration under these harsh operating conditions.
ALPHA OM-372 is designed for fine feature applications
ALPHA OM-372 is compatible with type 5 and 6 powders to enable excellent print and reflow attributes on the smallest feature sizes. This paste exhibits >90% transfer efficiency and superior print process stability with Cpk >2.00 on 008004 packages with 80x130µm pad sizes.
ALPHA OM-372 offers excellent coalescence on 80x130µm pad sizes with no evidence of post reflow defects.
