MGX QFN-11

Description

The MGX QFN 11 SIR test board reduces signal pin pitch over the four quadrants. As the signal pin distance between opposite conductors narrows, the potential for current leakage increases. The tighter pitch equates to increases in the cubic volume of flux residue.

MGX QFN 48-11 Chip

MGX QFN 48-11 Chip is one of the more challenging components to clean with a standoff gap lower than 50μms, flux residues bridge the lands and thermal lug. The residues tend to be active due to poor outgassing channels.

0508/10 PF-480 PF Capacitor Array Chip

Is a miniaturized cap with a very tight pitch between the conductors of opposite polarity. This design tests for fluid that can be trapped in the body of the component located under an RF Shield.
