Description
ALPHA OM-338 Solder paste Lead free
ALPHA OM-338 Solder paste Lead free is a no-clean solder paste designed for a broad range of applications. OM-338’s broad processing window is designed to minimize transition concerns from tin/lead to lead free solder paste. This material is engineered to deliver the comparable performance to a tin lead process.* ALPHA OM-338 yields excellent print capability performance across various board designs and, particularly, with ultra fine feature repeatability (11 mil Squares) and high throughput applications. Outstanding reflow process window delivers good soldering on CuOSP with excellent coalescence on a broad range of deposit sizes, exceptional random solder ball resistance and mid-chip solder ball performance.
ALPHA OM-338 is formulated to deliver excellent visual joint cosmetics. Additionally, ALPHA OM-338’s capability of IPC Class III for voiding and ROL0 IPC classifications ensures maximum long-term product reliability. *Although the appearance of these lead-free alloys will be different to that of tin-lead, the mechanical reliability is equal to or greater than with that of tin-lead or tin-lead-silver.
