What??? You don�t have enough things to monitor? The origin of some profiles is mysterious. It�s probably good to try to understand such mysteries. Certainly, the important determinants in the design of your reflow profile are: * Paste you�ve sel

How would you like to have this guy evaluate your reflow profile? It was in response to an auditor who require someone they had monitor temperature in both Fahrenheit and Celcius. What a geek Don't put him on the spot. That is not a good thing to

Jacky: There�re major four factors that affect the reliability of a solder connection. 1 Design of the connection including the shape and height of the lead and the type and amount of solder. 2 Dissolution of base metals into the solder connection.

Let�s not get drawn into making more of the amount of training required in order to be able to develop an effective reflow recipe than is necessary. A low-skilled operator with about one hour's training can setup the solder reflow oven. Consider co

You didn�t identify the type of tape you use, but Kapton or similar tape is not an effective method for attaching thermocouples. Search the fine SMTnet Archives for alternatives and comparison of methods. Two methods for mechanically attaching ther

Thought I would reply and try to assist. PROMATION, my company, also manufactures Diode Laser soldering systems but with this stated we also manufacturer iron tip systems, soft beam systems and hot air solutions. The reasons are simple. Diode Laser

| | We have some SMT components with gold plated leads. They're actually LCC led packages. A good solder alloy to use would be Indium / Lead to reduce tin dissolution into the gold and avoid the resultant brittle intermetallic compound. However, a re
