Dear Sirs,
My name is Evgheni Moscov, I'm production technologist of ADD-TECHNOLOGY SRL (www.addgrup.com), Kishinev, Republic of Moldova, Eastern Europe. Our profile is design, development, production, implementation and technical support of hardware and software for automated meter reading systems for energy resources consumption, made on the basis of advanced communication means utilization.
We often use SMD components, like BAV99LT1G, BC807-40LT1G and BC817-40LT1G.
We are developing a new device and plan to solder this type of components on solder wave machine. Solder wave temperature is 265-270 0С(deg. C). The board is double-sided mounted, to reduce the complexity of the PCB mounting, we’d like to solder THT and SMD components simultaneously on wave solder machine.
In this regard appears some questions:
• Since you are manufacturer of this components, what is your opinion about such way of soldering?
• Are this components suitable for wave soldering?
• This temperature, won't it affect the performance of the SMD components?
• Isn't this temperature critical? won't it cause the breakdown of the component?
Our task, is to understand, are this components suitable for wave soldering or only for reflow.
We are waiting for your comments, the question is very actual, please give us the answer ASAP.
Yes, you will have to secure the package (glue or clip) before using the wave flow process.
We have several customers who mount our parts with adhesives on the bottom of the boards prior to wave solder process. Typically we recommend a 260C peak wave solder reflow for 5-6 seconds.
Please refer to our soldering and mounting techniques reference manual at:

Let me know if you have any other questions.
