Problems to use lead free paste in PCB with Pb

Electronics Forum | Fri Jan 30 15:11:50 EST 2009 | joseluis_amper

Dear Sir. Recently we had a problem in our production. We had pcbs with no RoHs (with solder Pb in pads) but we used paste Lead Free. I want to know if we will have problems in this solders in the future, because (perhaps)the solder will be broken, o

Problems to use lead free paste in PCB with Pb

Electronics Forum | Tue Feb 03 03:35:30 EST 2009 | sachu_70

Hi Jose, such a process is possible, but you need to confirm that the PCB material has high Tg. In additon, you need to re-look solder paste printing parameters and make required changes in stencil apperture design for optimum solder volume. Just a

Using Automated 3D X-Ray Inspection to Detect BTC Defects

Technical Library | 2013-07-25 14:02:15.0

Bottom-termination components (BTC), such as QFNs, are becoming more common in PCB assemblies. These components are characterized by hidden solder joints. How are defects on hidden DFN joints detected? Certainly, insufficient solder joints on BTCs cannot be detected by manual visual inspection. Nor can this type of defect be detected by automated optical inspection; the joint is hidden by the component body. Defects such as insufficients are often referred to as "marginal" defects because there is likely enough solder present to make contact between the termination on the bottom-side of the component and the board pad for the component to pass in-circuit and functional test. Should the board be subjected to shock or vibration, however, there is a good chance this solder connection will fracture, leading to an open connection.

An Investigation into the Use of Nano-Coated Stencils to Improve Solder Paste Printing with Small Stencil Aperture Area Ratios

Technical Library | 2017-09-28 16:36:33.0

These nano-coatings also refine the solder paste brick shape giving improved print definition. These two benefits combine to help the solder paste printing process produce an adequate amount of solder paste in the correct position on the circuit board pads. Today, stencil aperture area ratios from 0.66 down to 0.40 are commonly used and make paste printing a challenge. This paper presents data on small area ratio printing for component designs including 01005 Imperial (0402 metric) and smaller 03015 metric and 0201 metric chip components and 0.3 mm and 0.4 mm pitch micro BGAs.
