What is the solids content of your solder? 50%??? Then, theoretically, if the aperture is 1:1, you'll have 2 thou of solder on your pads.

Dear All In future, we will switch our process from Reflow Soldering to Vapour Soldering. Very appreciated if someone can share with me his experince in advantage and disadvantage of using Vapour Machine. Thanks in advance.

In addition to reducing oxides my understanding is that nitrogen increases the surface tension of solder (I've also read the inverse). Bottom line, Nitrogen reduces rework, improves quality, improves solder appearance, and reduces maintenance. Shea

On our Pilarhouse Jade we use nitrogen to cool the belt that drives our solder pump as well as keep the amount of oxygen to a minimum in our solder pot to reduce dross.

We have a problems with soldering in the PCB in the Solder Wave process. Our pcbs are failures in the solder (voids) in the throughole components. The main problems is in varistor components. what are the soluctions to problems? tks

Hi Could any one please provide the name of companies doing solder dross analysis. Is there any standard kits available to take sample from solder baths. Thanks in advance for your help. Kgerry

Dear SMTNetters: Does anyone have a good method for determining the solderability of leaded high power resistors? We currently are using Dip and Look and they always pass yet solderability issues remain... Thanks! BWET

I see bare copper on top of some of the leads. Maybe that's normal and acceptable, but I would look at the underside (solderable surface) of the leads on some bare parts to make sure they're properly plated. Poor solderability can be one cause of v

Lead free solder does tend to resemble cold solder joints after processing. Generally, this is acceptable. The latest IPC 610 has pictures of acceptability of lead free solder joints, which you can use to compare to the joints that you are seeing o

Hi All My company is doing PCB assembly.To save cost, we change our wave solder bath from SnAg to SAC 305. What is the pros and cons for using SAC 305 solder? And,will affect to our quailty? Thanks in advance.
