You never mentioned the size of the board? You will find a vast array of pre-heaters with a range of prices. I could reccoment a few products based on the size of the board in question. The solder iron staying at temperature while not being used is a

I have been following this thread with a great interest. However, the rules or legislations that control RoHS standards is maybe questionable, but I can't see why people/companys have so hard to think about the "next generation"? The fact is: RoHS is

Hi, We have just recently ordered a pre-heater for repair. Our concerns is: What temperature shuld we working with? I reckon that it shuld/must be between 80-100 degr. Celcuis? And also; How are we dealing with the MS-level (RoHS compliant) componen

Thanks a lot guys. The part dims are in mm by the way. So last night i was looking at the .pcb file and saw that the pad size and stencil are both .013" while the ball on the BGA is .018" (sorry for switching from metric). Is this ok or can i have en

A 1:1 pad to ball diameter will cause the balls to collapse more giving you less post solder component standoff. Depending on the application of this product and required reliability, you may want to stay with the padstack being used. You may try c

Looked at it on the web, I believe that it will place those 600 parts in less than 2 hours! And you guys were thinking that it is slow? Ken, not only will it solder those parts with its blazing speed but did you know that you don't even need a sten

Cheers Jerry, forgot the most important one! Also want it to do: laser 3D volumetric solderpaste inspection Pre-reflow (including fault logging by placement machine & individual feeder) Post reflow solder joint inspection & handle lead free joints

The problem is that we don't use a wave solder machine. Our process right now is that we mask the holes, let it sit at room temperature until it dries, then conformal coat the boards with Humiseal. And, we cannot have the boards ready the day befor

I have been comparing Mirtec to Yestech on a regular basis. As a AOI trainer and installer, I have seen significant difference between the machines. 1. In a side by side comparison just today, using the same board, I found the following: a. Insp

Hi Kyle, Although I agree in principle with what you say, we were getting exellent solder joint inspection on reasonably high density boards (approx 1000 components from 0402 to finepitch QFP's). However obviously they wouldn't touch any form of BG
