Photo Angles

By Palesa Makhado, Ms

A practical note on board and defect photo angles, for teams that need useful images for setup, support and traceability.

Inspection goes wrong when the same board is photographed badly: glare over joints, no reference to component location, or close-ups that miss the wider assembly. Photo Angles sets out clearer ways for electronics teams to capture SMT and pick-and-place issues for quoting, support and line checks.

Take board images that will stand up later, not just look acceptable on a phone. Use it when documenting polarity mistakes, solder bridges, missing parts and feeder-related placement faults across Gauteng, KwaZulu-Natal and the Western Cape. Send the assembly context through the contact form.

Three shots every board needs

• Whole board image with orientation marked
• Defect close-up taken square to the part, with enough surrounding board visible to identify the location and nearby reference designators
• Drawing reference, Gerber view or BOM item noted so the image can be matched to the correct assembly record later
• Operator, technician or inspector name recorded clearly

For follow-up, pair this note with machine pages and fault records that use the same board reference. The journal is where image sequences make sense over a shift, while equipment pages identify the feeder, camera or oven section shown in the frame.

How Photo Angles help with AOI kit and bay records

Photo Angles explains how to take board and defect photos that are actually useful later. Good angles help with setup review, remote support and traceability instead of creating another vague image folder.

Start by capturing the full PCB on a plain background with one corner or connector visible for orientation. Then take a mid-range image that shows the affected area in relation to nearby components, fiducials or test points. Conditions on South African sites matter as well, because bright workshop lighting, coastal humidity, dust and backup power change how reflections and shadows land on solder joints.

Take the first usable image before anyone touches the suspect area with tools or flux. That untouched record helps when a support query later asks whether the fault came from print, placement or rework. Save the file with the board code, side and date so it does not disappear into a generic camera folder.

Lighting and site conditions in SA

Many board photos fail because the bench light is directly above the joint, washing out fillets and pad edges. On older factory sites and mixed-use workshops, overhead fittings, window glare and handheld torches can all distort what the camera sees. Say whether the image was taken at incoming inspection, first article, in-process check or rework, because that context changes how the fault should be read.

At coastal plants, oxidation and surface residue can look worse in a flash photo than they do under magnification. Inland dust settles on darker solder mask and often creates false texture in wide images. During power interruptions or generator changeover, take another reference shot once stable lighting returns so the record stays consistent.
