Can anyone provide a list of the top 5 solder paste / wave flux manufacturers by sales? We are evaluating changing to a new chemistry and would like evaluate several of the top manufacturers. Thanks.

Hi, Actually, we want to run a benchtest for solder paste to verify if the paste we use is one of the best. So, with your experiments and tests, what's the top 5 for No-clean solder paste? * I mean leaded solder paste ( for the moment) :)

Am looking for a table top mini wave to remove connectors or solder in connectors in hard to reach areas. Can anyone recommend a good brand. Thanks

Hi, We are a Contract Manufacturing and have a project which has a few Xilinx BGA on top and bottom side. Does anyone run a cross this or have any suggestion on how to reflow them. Thank you, -Michael

Does anyone know of an inexpensive table top router for singulating pcb's? We have a very small volume appication and a need for a prototype singulation tool. Thanks John S.

Hi, Is there any special temperature setting for example , bottom temp should be lower than top temp to prevent component drop. Or any information that can help to prevent component from drop off during reflow of top side.

Try using the loctite(glue) during the top side process. Other way is to separate bigger component IC on the last process (top side).

You need a machine with side clamps. DEK makes them. MPM makes them. Look into a retro for your machine. Both take up space on top of your board. Be carefull of top side component clerance if switching.

Shouldn't the top of the board be at the exact same height as the top of the side clamps? Why are the clamps holding the stencil up off the board?
