NXP QFN Solderability Wetting Problems, Kester

Electronics Forum | Mon Aug 14 14:53:51 EDT 2017 | emeto

AIM, Indium , Alpha will be your top 3 choices. I did paste evaluation before with 4 paste manufacturers and Kester was my choice number 4. Profile according to the paste specs and observe results.

How do you evaluate the soldering quality for those QFNs? X-Ray or AOI? For some QFNs (and other bottom termination components) it's not supposed to have solder fillets on toes. It's also noted in IPC-A-610 (Rev.F 8.3.13). Take a look at your QFN ch

Key Advances in Void Reduction in the Reflow Process Using Multi-Stage Controlled Vacuum

Technical Library | 2020-01-28 00:23:58.0

This paper explores new advances in the reflow soldering process including vacuum technology and warpage mitigation systems. The first topic for discussion will be the implementation of a vacuum process directly in a conventional inline soldering system. The second topic presented is the mitigation of warpage on substrates or wafers.

Advanced Solder Paste Dispensing

Technical Library | 2008-10-15 20:16:12.0

Solder paste dispensing is usually considered a slow process. Due to the speed advantages, screen printing is used to apply solder paste whenever possible. However, screen printing is not always an option. Leveraging the high speed of piezo drive technology opens the door to a broad range of solder paste dispensing applications. The ability to dispense dots under 300-μm diameter, even as small as 125 μm, enables BGA rework, small geometry deposits for miniaturized passive components, electrical connections in recessed cavities, and RF shield attach for handheld devices.
