Understanding both sides of the Buy/Sell Process

It would be nice if you could google an accurate PCB Assembly price. However, board specifications and manufacturing requirements differ, not to mention the volatile market conditions of COTS. Many self-service quote modules currently used on websites do a decent job on pricing the bare boards, however they fall short when pricing Turnkey assemblies.

Eventually, the gaps between what was quoted online and the actual PCBA manufacturing cost surface. This ultimately happens after the review of your Gerber files and Bill of Material. At this point you have invested a lot of time with less than a favorable result. What’s worse is that you may have already plugged these estimates into your product development plan requiring you to back track.

We believe the fit between two companies is the basis of a success relationship. Needs and processes are not always in alignment between customers and suppliers. Unfortunately, these are not always uncovered until after a project gets underway. This is not the best time to figure this out.

Making sure the OEM and the Contract Manufacturer are on the same page before embarking in the quote process is the start of a transparent relationship and ultimately saves time. Understanding the process from both the buyer and seller perspective up front, will make for a successful relationship that’s a win-win with long term success.

Highlighted below are the items Altek discusses when working with a prospective customer. Not only are these important conversations for Altek to have with its customers, but important points to consider when evaluation any Contract Manufacturer. Getting this information on the table helps determine the customer/supplier fit before proceeding with the quote process.

These items are important pieces of the Total cost of ownership evaluation process of a new supplier. This information exchange process works, and it will allow you to eliminate sub-standard suppliers before starting the bid cycle. None of us have time to waste as referenced by Benjamin Franklin quote…“Remember time is money”!
