MLT provides laser services for selective solder mask removal as a precise and controlled rework option. No more scrapping or tedius hours to rework selective areas to recover simply unwanted solder mask. This same process works from many other mat
SIPAD Solid Solder Deposit (ssd) is a Siemens patented process that pre loads the pc board surface mount pads with solder in a solid form. Boards are printed, reflowed without components producing a predictable repeatable meniscus. SIPAD boards a

Hi guys, I really am at a loss to understand this one. It would appear that there may be some reaction between the flux and the resist? Or maybe you have an OSP on the board that is reacting during soldering? As a fast fix, maybe you should try a

Cleanliness is a product of design, including component density, standoff height and the cleaning equipment’s ability to deliver the cleaning agent to the source of residue. The presence of manufacturing process soil, such as flux residue, incompletely activated flux, incompletely cured solder masks, debris from handling and processing fixtures, and incomplete removal of cleaning fluids can hinder the functional lifetime of the product. Contaminates trapped under a component are more problematic to failure. Advanced test methods are needed to obtain "objective evidence" for removing flux residues under leadless components.Cleaning process performance is a function of cleaning capacity and defined cleanliness. Cleaning performance can be influenced by the PCB design, cleaning material, cleaning machine, reflow conditions and a wide range of process parameters.This research project is designed to study visual flux residues trapped under the bottom termination of leadless components. This paper will research a non-destructive visual method that can be used to study the cleanability of solder pastes, cleaning material effectiveness for the soil, cleaning machine effectiveness and process parameters needed to render a clean part.

. Does Solder Mask Color Matter? The color on a printed circuit board is a solder mask, solder resists, or solder stop mask. A solder mask is a thin layer of polymer that protects the copper traces printed onto the board from oxidation, as well as prevents solder bridges

Some applications that fall under the RoHS directive are exempt from being lead-free because the reflow temperature requirements can only be met with high-lead solder alloys which are exempt under RoHS regulation
