I see these white/cream colored blobs all over the board (I've surrounded them with red rectangles in the image above), something which I've never encountered before. They're plastic like in texture, deforming with small amounts of pressure applied to them. Does anybody have any idea what these might be, and whether or not they're indicative of some kind of failure?
My motorcycle's EFI control unit is complaining about not getting enough supply voltage (it is, I've checked the input pins) after breaking down recently (and this is now preventing the bike from starting up), so I figured this electronics degree must be worth something, right?
Hoping it might be as simple as a blown capacitor or damaged track, I removed the control unit from my bike and pried off the metal cover covering the pcb, which was attached with some kind of waterproof sealant (somehow without damaging the circuit board myself). The image below is what I found myself presented with.
Also, if anybody happens to notice anything obviously wrong in the circuit board above, I'd appreciate very much if you could post a comment and let me know!
p.s. The supply rails on either side of the board measured ~5mV across with the bike's ignition turned on (what the hell? basically nothing). The Infineon CPU seems to be rated for 3.3V of supply voltage... so one thing I tried was putting a small 3V DC supply in parallel across the rails, hoping it might stop complaining about having low voltage (it didn't), was this stupid? Yes it was.
