Basic Solder question
Hello everybody, I am just starting to solder the DB9 connector on and I noticed that the solder mask is turning a darker blue and it is "bubbling" for lack of a better term. I tried putting a picture with this post, I think it worked. Any and all criticism is welcome! Thank you so much!

Re: Basic Solder question
Too much heat, IMO!
What size tip? Variable temp Iron?

Re: Basic Solder question
Ok so I got curious and found that the heat actually had no affect on the PCB. What I was seeing has been caused by the flux! 
Thank you so much Ken!

Re: Basic Solder question
Are you using lead free solder? If so, don't. It melts at a higher temperature then leaded. Buy a reel of 0.8mm diameter 60/40 leaded multicore from a proper electronics supplier. Most common multicore solder is larger in diameter than the the ideal for this sort of job.
