Has anyone seen a good guide/s on reflowing? ive been looking around a bit but most of the information is 50/50, seems like nobody WANTS to write a guide. if any of you guys have an idea on this, it would be extremely appreciated.

Re: Reflowing
Information is power $$$
You'll probably never find a one-fit solution to reflowing/reballing as ALL components vary.
The best way to learn it yourself is to buy yourself an IR/Reflow station and toy around settings.
But if you go by theory (lead-free vs lead solder) you'll find "reflow/reball" profiles on the web.
Achieving a profile curve, meanwhile, is an art... -

Re: Reflowing
Get the tools and play around
I killed many BGA components when first learning! Too much heat, too long with heat, Not right curve, Not enough heat etc etc etc
After much practice I can successfully reflow with hot air.... And for the first time managed to do a complete reball and flow using nothing but hot air and no templates, or balls, or anything else fancy
No idea how much life the GPU has left now though! HAHA but thought id have fun trying it out

Hi everyone, I’m working on an HP Victus 15 motherboard that previously had a strong short-circuit on 19v line. The laptop now powers on, but system performance is extremely slow and laptop works only on AC adapter
This are Important PIN Voltage Measurements (ISL88739 Charging IC)
1 ACIN 2.08V
2 ACOK 2.94V
3 SDA 3.28V
4 SCLK 3.28V
5 #PROCHOT 0v
10 COMP 0V
11 CCLIM 4.14V
12 FSET 0V
13 BATGONE 0V
16 ACLIM 2.48V
17 NTC 1.60V
18 DCIN 19.51V
20 VDDP 5.15V
21 LGATE 0V
22 PHASE 0V
23 UGATE 0V... -
Here`s a quick ME Firmware cleaning guide.
The guide is basic,its main goal is to show you how to use intel FIT,its highly recommended that you all follow the guide posted at win-raid
(The attached FIT version is 11, if your ME Firmware (FW) is not 11.0.*.* follow the win-raid guide. Use the tools version for your ME FW, for example: ME System Tools v9.1 For systems running ME v9.0 - v9.1)
A video,software (intel FIT) and practice bios are all included. I`ll post a better video and more advanced guide at a later date.
1. Open the... -

I have recently come into possession of a G14 that cannot detect or charge it's battery. Initially both windows and the bios agreed that the battery was on "0%" but the laptop was able to run without AC power. I was able to get the laptop to detect the true charge of the battery(26%) in windows for a moment but it wouldn't charge or update the percentage when the battery drained. I attempted a few more EC resets and battery reconnections and now the battery shows at 0% in bios and 100% in windows. Additionally the machine is extremely laggy when plugged into AC. When on ac power in the... -
Hi everyone,
I have a Dell Inspiron 15 3511 that stopped turning on after my friend plugged in the power adapter.
Here’s what I’ve checked so far:
No reaction when pressing the power button (no LEDs, no fan).
The power adapter works fine (tested).
One chip gets extremely hot as soon as I plug in the charger.
The capacitors around that area are not shorted.
I’m attaching photos of the board to show the issue.
Based on this, what kind of fault or defective component could be related to this overheating?...
