Hi Guys, We prints solder paste on via hole as the holes are used as the test points. This is a clean process. In normal production, upon completion of a primary side, board will proceed to secondary process immediately. The problem happened when

Quad Flat No Leads (QFN) package designs receive more and more attention in electronic industry recently. This package offers a number of benefits including (1) small size, such as a near die size footprint, thin profile, and light weight; (2) easy PCB trace routing due to the use of perimeter I/O pads; (3) reduced lead inductance; and (4) good thermal and electrical performance due to the adoption of exposed copper die-pad technology. These features make the QFN an ideal choice for many new applications where size, weight, electrical, and thermal properties are important. However, adoption of QFN often runs into voiding issue at SMT assembly. Upon reflow, outgassing of solder paste flux at the large thermal pad has difficulty escaping and inevitably results in voiding. It is well known that the presence of voids will affect the mechanical properties of joints and deteriorate the strength, ductility, creep, and fatigue life. In addition, voids could also produce spot overheating, lessening the reliability of the joints.
QFN stenicl bumping process demonstrated using a polyimide stencil. This process is one in which a stencil is used to the bump the bottom terminations of a leadless device making it simple to place without voiding of the the thermal pac or shorting o
