Working with a PCB assembler shouldn’t feel like a guessing game. Yet many designers end up frustrated—waiting for updates, fixing miscommunications, or even redoing batches because small details were missed. The truth is, great PCB assembly isn’t just about the assembler’s skills—it’s about how well you work together. Let’s break down the steps to turn your partnership into a seamless process.
Nothing slows down assembly like incomplete or confusing files. An engineer once sent a BOM (Bill of Materials) with missing component footprints—only to have the assembler pause production for 3 days to ask for clarification.
To keep things moving:
-
Double-check that your BOM matches your Gerber files (same part numbers, values, and footprints).
-
Include a “readme” for tricky parts: e.g., “This connector needs to be soldered at an angle, not flat.”
-
Use standard file formats (most assemblers prefer Gerber 274X and IPC-7351 for footprints).
A little file prep upfront cuts days off your timeline.
Jumping straight to mass production is a risky move. A startup once ordered 500 assembled boards without testing a prototype—only to find the LCD screen didn’t fit (the footprint was slightly off). They had to scrap all 500, costing thousands.
Always start with a small batch (5-10 boards). It lets you:
Delicate or custom parts (like sensors, RF modules, or heat-sensitive ICs) need extra care. A designer once sent a batch of temperature sensors to an assembler—only to have half of them damaged during soldering (the assembler used too high a temperature).
Be clear about special requirements:
-
Note temperature limits: e.g., “This IC can’t exceed 240°C during soldering.”
-
Specify handling rules: e.g., “These RF modules need anti-static packaging until assembly.”
-
Share datasheet snippets for unique parts—assemblers can’t read your mind, but they can follow clear instructions.
A common mistake: thinking your job ends when the boards ship. But what if 10% of the boards fail after you receive them? A hobbyist once faced this—their assembler refused to help, leaving them to debug alone.
Choose assemblers that offer post-assembly support:
-
They help troubleshoot if boards fail (e.g., “Let’s check if the solder joints on the power IC are okay”).
-
They replace faulty boards (within a reasonable warranty period) if the issue is their mistake.
-
They share test reports (like AOI results) so you have a record of quality.
PCB assembly is a team sport. By prepping your files, testing small batches, clarifying special component needs, and choosing an assembler with support, you’ll cut delays, avoid waste, and get boards that work exactly as you designed. It’s not about being perfect—it’s about making collaboration easy for both sides.
