Hello all, I am having soldering issues with an Everlight component it is a TM4201/TR2 (Right angle IRDA with a 1mm pitch). The problem I have is that after reflow the solder joints look perfect, but during test we are losing 7 micro amps as soon as

Here is a nugget from the Data Sheet... Wave Soldering: Excess moisture on the PCB during soldering may lead to random solder balling and poor wetting of some solder joints. IT IS IMPORTANT that the flux solvent carrier (water) is fully evaporated a

Haris: On your soldering issues, we don't know the make-up of your component. We don't know the type solder balls on the component. We don't know the solder paste you plan to use. Your component and paste supplier are better sources for this type o

First of all, more info is needed. Solder shorts can be caused by much more than flux. Is the solder short always in the same spot or all over the place? More detail please.

Sounds like possibly too little preheat. Russ

Still confused what you are trying to say? And I didnt get the answer regarding soldering profile.

Do you have any experience with flip chip applications using lead-free solder, and specifically do you have any information revealing how the process parameters for standard air reflow atmosphere can be modified to match the results for solder reflow

Hi, I have a lot of solder bridge in our wave soldering process.We use SACX0307 and Surf 11 flux.the SW mashine is Vitronics delta 6622.Itry to change flux and termoprofile but results is not god.Can you halp me - recommend me some flux or other adv

Likely causes of this are: -Preheat temp. too low -too much dross -uncured epoxy -PCB contamination ...also varify the solder flow over the wave is smooth.
