Using ERSA Ecoselect. I am curiuos to hear from other selective solder users as to what is the ideal lead lenght for your application on thru hole components. Shorter leads have helped us decrease solder bridges. We find ours to be from .75 mm to 1

When bridging becomes an issue, I like short leads. Lead Free is where I see most bridging occur. Usually when lead length starts to approach lead spacing. As long as the lead is discernible in the joint, it's acceptable. If you are having troubl

Hello. We encountered a SMD problem on PCB. It is that the lead of photocoupler is shifted after reflow and don't meet the minimum requirement of side joint length. I know this is a defect but what i want to hear the reason and the solution to prev

Basically, it's a tilting problem of certain devices. Usually with axial by-pass caps tilting, which pulls the lead up through it's mounting hole. Other problems with components with leads cut to lenght to eliminate post-wave trimming. All suggestion

Hello, I am not familiar with Inertec but have some expirience with selective soldering process, My oppinion is that the wave and slective soldering are not the same game. In Selctive soldering process is very important the layout design. If use th

This has always been a big debate on what is better. Few things to consider before getting into number of zones. What is the throughput and cooling requirements? Throughput is a direct relation to length of heating zone. Longer heating length
