M8 SN63/PB37 T4 NO CLEAN SOLDER PASTE

M8 SN63/PB37 T4 NO CLEAN SOLDER PASTE

Clock fast Lead Time: In Stock Pdf file Data Sheet Pdf file SDS

An evolution of the highly successful NC258 platform, M8 brings no clean solder paste performance to the next level. Developed in combination with T4 and finer mesh leaded alloy powders, M8 provides stable transfer efficiencies required for today’s UFP and umBGA devices, reducing DPMO on the most challenging applications.

A novel activator system provides powerful, durable wetting action accommodating a wide range of profiling processes and techniques. M8 activators will reduce wetting related defects such as HiP (head-in-pillow) and provide smooth shiny joints. M8 has reduced BGA and BTC voiding to as low as <5% on BGA and <10% on BTC ground pads.

HANDLING & STORAGE

Parameter Time Temperature
Refrigerated Shelf Life 1 year 0°C-12°C (32°F-55°F)
Unrefrigerated Shelf Life 3 months < 25°C (< 77°F)

Do not add used paste to unused paste. Store used paste separately; keep unused paste tightly sealed with internal plug or end cap in place. See AIM’s paste handling guidelines for further information.


CLEANING

Pre-Reflow: AIM DJAW-10 effectively removes M8 solder paste from stencils while in process. DJAW-10 can be hand applied or used in under stencil wipe equipment. DJAW-10 will not dry M8 and will enhance transfer properties. Do not over-apply DJAW-10. Do not apply DJAW-10 to stencil topside. Isopropanol (IPA) is not recommended in process, but may be used as a final stencil rinse.

Post-Reflow Flux Residue: M8 residues can remain on the assembly after reflow and do not require cleaning. Where cleaning is mandated, AIM has worked closely with industry partners to ensure that M8 residues can be effectively removed with common defluxing agents. Contact AIM for cleaning compatibility information.
