temperature range

Electronics Forum | Mon Nov 20 04:39:19 EST 2000 | SV

Hello, I have to design a PCB for which the customer have the following temperature requirements: -55degC to +85degC operating temp. -61degC to +125degC storage temp. My question is: does the FR4 material meet this conditions? Which are the parame

Die temperature exceed Tg temperature

Our company is assembly flip chip on flex, we have new design of flip chip which die temperature will increase until 145 degree C after test run the end product, however the Tg,glass transition temperature is 148. Will this case causing any reliabil

Die temperature exceed Tg temperature

Take your choice: * Can't image this is a good thing. The board under the die will 'dry-out' and turn brittle over-time. It's possible the way attachment glue bonds to the board will change as the board dries-out. * Epoxy suppliers pad their number

Wave soldering temperature

Is 260 degrees C / 500 degrees F the optimum temperature for wave soldering ?

Humidity and temperature

Electronics Forum | Wed Sep 14 04:09:21 EDT 2016 | jimmyh

We are enclosing our SMT room and will control the Humidity and Temperature of the room. Is there a standard for humidity and temperature for a SMT room and if so what is it. What is protocol if it goes out of tolerance? Do we stop production? Is

SMT component temperature spec

Electronics Forum | Mon Mar 04 13:13:52 EST 2019 | scotceltic

What temperature spec are people using in the industry to make sure an electronic component is SMT reflow compatible ? Ex. I have some parts that I want to possibly process as Pin in Paste but am not sure what temperature ratings the plastic will m

Solder bath temperature

i have an issue with solder bath temperature. there is a big difference in temperature of alloy in the middle of the bath and at the ends(about 35C). i took down heating elements for inspection and they look fine. its just that most of the heat is cr

Solder bath temperature

Electronics Forum | Thu Jan 26 13:13:14 EST 2017 | dyoungquist

What type of solder are you using, Lead or Lead-Free? What is the melting point of it? What temperature are you setting your solder bath to? Possible solutions: 1) Give your solder bath a little more time to even out the temperature across the en

Wave soldering preheat temperature

If you will place a temperature strip on the board during wave soldering process you will get a max of 210 F or 98.8 C which is normal on the standard wave temperature. The problem on the 10% solder on the TH via hole can be caused by insufficient fl

reflow / soldering temperature

Electronics Forum | Thu Apr 05 10:50:08 EDT 2001 | CAL

Per our staff here at ACI......... Higher Temperatures maybe necessary to achieve good solder process results. The alloy formed when HASL coating protects the copper is the same as that when OSP provide protection. Temperatures may be increased to im
