Current Standards for Circuit Card Rework and Repair of Airline Avionics.

[kontiki99]

Twenty something years ago, the shops I was supporting at an airline wire using IPC 610 standards for circuit card repair and rework. I've been away from that level of repair since.
Anyone know what current industry standards might be?

I'm trying to develop approved line repairs that could involve repair of broken traces on cockpit light plates.

To update, I got everything I need from a Copilot query, I'd delete this post if I could quickly see how to do that.
Apologies.

Or, you could share what you've learned....

BTW... What is a "Copilot inquiry"????

BTW... Your question is a bit odd... I have dealt with lightplates and fundamentally a lightplate is a plastic façade with specific coating layers and engravings thru the coatings and a simple backside electrical panel... with lighting to illuminate the controls, and knobs, etc... with variable intensity adjustments... and or linked to a control function. There are companies which will fully 'rehab', 'rebuild' or 'make-new' lightplates.
A night cockpit video... constant luminosity lightplates 'on' all over the cockpit...

Copilot is Microsoft's AI.

WK,

Cockpit light plate repair is not complex. Typically, there isn't enough profit to support a large repair base for minor parts used on small fleets of old aircraft. Regulations for approved parts on certificated airplanes still exist though.

Support gets thinner when supporting a fleet of old aircraft made up of lease return aircraft already operated by a number of different operators. The light plate panels on any two aircraft may not be exactly alike.

An inoperative light plate can ground an aircraft though. I'm getting ready to author a company approved repair procedure that can be accomplished on the line. Rules of company I work for require that I document the substantiation for what I approve.

I see no reason a hangar mechanic can't repair a broken/lifted trace as well as a cracked solder joint. The standards I saw supporting a back shop at Delta Airlines a couple decades ago were IPC 610/IPC 7711? Unfortunately, our standards subscription does not include those documents. I'll find something though.

The aircraft OEM standard soldering procedures get me most of the way there. A lifted/broken trace might be a stretch for a Tech more used to landing gear work.

Copilot is the AI query tool included in the company's Microsoft Office 365 subscription. I think it works better than a basic search engine query.

Like I said earlier... lightplate repairs/overhaul/replacements are a niche-specialty... especially when it comes to matching color and luminescence.

I found a shop in Wichita KS that does this as a business... especially for low quantity [onsey-twosy] work.

Where I work now, there is a 'back-shop' dedicated to lightplate fabrication... due to high qty-required to maintain old MIL Acft.
